both sides are equal.
Step-by-step explanation:
Assumption: Prove that both sides are equal
Q) 5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13
1. Open the brackets on both sides
5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13
-15x - 10 - x + 3 = -16x - 20 + 13
2. Bring all x variables on the left side of the equation
-15x - 10 - x + 3 = -16x - 20 + 13
-15x - x + 16x = -20 + 13 + 10 - 3
3. Solve to prove
-15x - x + 16x = -20 + 13 + 10 - 3
-16x + 16x = -23x + 23x
0 = 0
Therefore, both sides are equal.
