Expand
5x - 5 + 3 = 7x + 7
Simplify 5x - 5 + 3 to 5x - 2
5x - 2 = 7x + 7
Subtract 5x from both sides
-2 = 7x + 7 - 5x
Simplify 7x + 7 - 5x to 2x + 7
-2 = 2x + 7
Subtract 7 from both sides
-2 - 7 = 2x
Simplify -2 - 7 to -9
-9 = 2x
Divide both sides by 2
-9/2 = x
Switch sides
x = -9/2
- (Decimal Form: -4.5)
Answer:
x = -4.5
Step-by-step explanation:
1. Distribute.
5x - 5 + 3 = 7x + 7
2. Combine like terms:
5x - 2 = 7x + 7
3. Subtract 5x from both sides.
-2 = 2x + 7.
4. Subtract 7 from both sides.
2x = -9.
5. Divide all sides by 2.
x = -4.5
