Question

11.3(-10x - 3) + 6x = 75

Answer 1

`\huge\boxed{x=-(7)/(2)=-3.5}`

Explanation:

`3(-10x-3)+6x=75\qquad/\text{use the distributive property}\\\\(3)(-10x)+(3)(-3)+6x=75\\\\-30x-9+6x=75\qquad/\text{add 9 to both sides} \\\\(-30x+6x)-9+9=75+9\\\\-24x=84\qquad/\text{divide both sides by (-24)}\\(-24x)/(-24)=(84)/(-24)\\\\x=-(84:12)/(24:12)\\\\x=-(7)/(2)`
