Question

What is 1/3 (5x+1)= -2

Answer 1

`\large\boxed{x=-(7)/(5)=-1.4}`

Explanation:

`(1)/(3)(5x+1)=-2\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot(1)/(3\!\!\!\!\diagup_1)(5x+1)=(3)(-2)\\\\5x+1=-6\qquad\text{subtract 1 from both sides}\\\\5x+1-1=-6-1\\\\5x=-7\qquad\text{divide both sides by 5}\\\\(5x)/(5)=(-7)/(5)\\\\x=-(7)/(5)`
