✔ 最佳答案
5(x-4)=35
5x-20=35
5x=55
x=11
First you need to devide both sides by 5.
This gives you (x-4) = 7 Remember when it says 5(x-4) it means the 5 is multiplying the whole thing, so you can simply divide the whole thing by 5.
So X-4 = 7
Add 4 on both sides
X=11
5 x - 20 = 35
5 x = 55
x = 11
5(x - 4) = 35
5*x - 5*4 = 35
5x - 20 = 35
5x = 35 + 20
x = 55/5
x = 11
multiply (x-4) by 5
(5)(x)-(5)(4) = 35
5x - 20 = 35
5x = 35 + 20
5x = 55
then 55 divide by 5
x = 55/5
x = 11
That it!
5x - 20 First use the distributive property
No like terms Combine like terms (if there is any)
5x - 20 Change the opposite of the number to addition.
5x + 20 Add the 20 to the 35 and you get 55.
5x = 55 Divide each side by 5
x = 11
First distribute the 5 to the x and the -4
So 5 times x equals 5x
5 times -4 equals -20
So you have:
5x-20
Add 20 to both sides of the equal sign:
5x-20=35
+20 +20
5x=55
Divide both sides of the equal sign by 5
This is your answer:
x=11
Distribute the 5 like this:
5x-20=35
segregate the -20 by adding 20 to both sides
5x-20+20=35+20
5x=55 after combining like terms
divide both sides by the coefficient
5x/5=55/5
x=11
First multiply 5 by x and -4. so 5(x - 4) would turn into 5x-20
so now you have
5x-20=35
add 20 to both sides which will cancel the first 20 leaving you with
5x=35+20
35+20=55 so
5x= 55
then divide by 5 on both sides so
x=11
