Answer:
x-7
Step-by-step explanation:
Simplifying
25 + -3x = 4
Solving
25 + -3x = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-25' to each side of the equation.
25 + -25 + -3x = 4 + -25
Combine like terms: 25 + -25 = 0
0 + -3x = 4 + -25
-3x = 4 + -25
Combine like terms: 4 + -25 = -21
-3x = -21
Divide each side by '-3'.
x = 7
Simplifying
x = 7
