Answer: x = 3
Step by step
5 ( –1x + 5) = 10
(1) Distribute
= – 5x + 25 = 10
(2) Subtract 25 from both sides of the equation
= –5x + 25 -25 = 10 – 25
(3) Simplify
= –5x = – 15
(4) Divide both sides of the equation by the same factor
= –5x/–5 = –15/ –5
(5) Divide the number
= x = –15/–5
Answer: x = 3
