find the value of x in the equation4(3x+7)=136?

Hi,

For this question, let's first divide both sides of the equation by 4 to get:

3x + 7 = 34

Now, subtract 7 from both sides to get:

3x = 27

Finally, divide both sides of the equation by 3 to get:

x = 9 <==== FINAL ANSWER

I hope that helps you out! Please let me know if you have any other questions!

Divide both sides by 4

3x + 7 = 34

3x = 27

x = 9

3x + 7 = 34

3x = 27

x = 9

4(3x + 7) = 136 [ Firstly, open the brackets on the left side ]
12x + 28 = 136 [ Take + 28 on other side and change its sign ]
12x = 136 - 28
12x = 108 [ Divide by 12 on both sides to get value of x alone ]
x = 108/12
[ x = 9 ]
hope i helped

4(3x + 7) = 136
12x + 28 = 136
12x = 108
x = 9

4(3x + 7) = 136
3x + 7 = 136/4
3x + 7 = 34
3x = 34 - 7
x = 9

4(3x+7)=136
Divide both sides by 4
(3x + 7) = 34
Subtract 7 from both sides
3x = 27
Divide both sides by 3
x = 9

take the 4 to right side
=>3x+7=136/4
=>3x+7=34
=>3x=34-7
=>3x=27
so x=9

EQUATION 4(3x + 7) = 136 you will multiply the 4 with what's interior the bracket. you're able to get 12x + 28 = 136 then you assemble like phrases 12x = 136 - 28.( the 28 turns into detrimental becus you have carried it over the = sign) 12x =108 now get rid of 12 as a fashion to locate x. 12x/12 = 108 /12 cancel (12 into 12 =one million and 12 into 108 =9) answer x =9.

this is very simple and basic. and important. drill it into your head you will need it for the rest of your life

4(3x+7) = 136 normally when you change side if its product or division, the numerator goes to den and vice versa . also if its addition, subtraction, you will need to change the sign when you carry it over. so we can write 3x+ 7 = 136/4 ( 4 comes down since you changed sides ) = 34
now look at 3x+7 = 34 or 3x = 34 - 7 ( you changed the sign from +7 to -7 when u changed the sides) or 3x = 27 or x = 27/3( 3 comes down when u changed side) or x = 9.

if you think this is the stupidest explanation you have heard and cant follow, then let us look at it in another way

4(3x+7) = 136. the left hand side and right hand side are equal. and if you do the same thing to both sides it has to remain equal to one another. our objective is to discover x , so let us try to simplify it

divide both sides by 4
4(3x+7) /4 = 136/4 ( SAME OPERATION ON BOTH LHS AND RHS)
we will get 3x+7 = 34
now let us subtract 7 from both sides we will get 3x+7-7 = 34 - 7 or 3x = 27

now let us divide both sides by 3, you will get x = 9

hope this helps. all the best
