4x-7=25
What is the value for the variable given? *

x = 8

Step-by-step explanation:

First write out the equation 4x - 7 =25

Next add your constant (7) on both sides since the problem is subtracting by 7. That would look like:

4x - 7 = 25

    +7  = +7

The 7s cancel out so that leaves you with 4x = 32

Now since the variable (x) is being multiplied by 4 you are going to divide by 4.

4x divided by 4 cancels out

32 divided by 4 equals 8!

hope this helps have a wonderful day!
