3+5x-7x=-5?

- 2x = - 8
x = 4

3+5x-7x=-5
3-2x = -5
2x = 3- -5
2x = 8
x = 4

3+5(4)-7(4)=-5
3+20-28 = -5
23-28 = -5
-5 = -5

x = 4

3 + 5x - 7x = -5

3 - 2x = -5

-2x = -8

x = 4

that's it! ;)

3 + 5x - 7x = -5
5x - 7x = -5 - 3
-2x = -8
x = -8/-2
x = 8/2
x = 4

3+5x-7x=-5

3-2x=-5
3+5-2x=
8-2x=0
4-x=0
4=x

check:
3+5x-7x=-5
3+5(4)-7(4)=-5
2+20-28=-5
2-8=-5
-5=-5
correct

5x-7x = -5 -3
-2 x = -8 * divide by -2
x=4

X = 4
-3+3+5x-7X=-5-3
5x-7x=-8
-2x=-8
x=4

Use your order of operations and combine like terms.

3 + (5x -7x) = -5 Combining 5x and -7x leaves you with -2x
3 + (-2x) = -5 Subtract 3 from both sides of the equation
-3 +3 + (-2x) = -5 - 3

- 2x = -8 Divide both sides by -2
x = 4

3 + 5x - 7x = -5

subtract 3 from both sides

5x - 7x = -5 - 3

-2x = - 8

divide both sides by -2

x = -8/-2

x = 4

5x-7x=-5-3
-2x=-8
-x=-4
x=4

3 + 5x - 7x = -5

first thing is to group like terms. meaning, add all x and all constants.

by transposition, transfer 3 to the other side and dont forget to change the sign.

5x - 7x = -5 -3

then do the operations...

-2x = -8

after that, divide the whole equation by -2 to get x

x = 4

to check, substitute the value of x...

3+5x-7x = -5

3+ 5(4) - 7(4) = -5

23-28 = -5
-5 = -5
