Answer:
Step-by-step explanation:
Prove that,
−5(x+8) = −25 then x = -3
−5(x+8) = −25
By distributive property,
-5x - 40 = -25
Adding 40 to both sides, that is, Additive property of equality
-5x - 40 + 40 = -25 + 40
-5x = 15
Divide both sides by -5, that is Division property of equality
-5x / -5 = 15 / -5
x = -3
Hence, x = -3 has been proved
Answer:
Statement Reason
1. -5(x+8)=-25 Given
2. −5(x+8) −5=−25/−5 Division Property of Equality
3. X+8=5 Simplifying
4. x+8−8=5−8 Subtraction Property of Equality
5. x=−3 Simplifying
