4(x-2)-3=9
Reorder the terms:
4(-2 + x) + -3 = 9
(-2 * 4 + x * 4) + -3 = 9
(-8 + 4x) + -3 = 9
Reorder the terms:
-8 + -3 + 4x = 9
Combine like terms:
-8 + -3 = -11
-11 + 4x = 9
Solving:
-11 + 4x = 9
Add '11' to each side of the equation.
-11 + 11 + 4x = 9 + 11
Combine like terms: -11 + 11 = 0
0 + 4x = 9 + 11
4x = 9 + 11
Combine like terms:
9 + 11 = 20
4x = 20
Divide each side by 4.
x = 5
