Answer:
x = 25
Explanation:
75 = (4x - 25)
Since there are no numbers outside of the parentheses, we can remove them.
75 = 4x - 25
Now we can see that we can add 25 to both sides.
100 = 4x
Divide both sides by 4 to isolate x.
25 = x
Check by plugging in the value into the original equation.
75 = 4(25) - 25
75 = 100 - 25
75 = 75
Your answer is correct.
Hope this helps!
