Answer:
x=-16
Step-by-step explanation:
We are given with the equation
[tex]40=-\frac{1}{3} \times (9x+30)+2 [/tex]
We are asked to solve it for x.
Distributing [tex]\frac{1}{3}[/tex] over bracket and simplifying
[tex]40=-(\frac{9x}{3}+\frac{30}{3})+2[/tex]
[tex]40=-(3x+10)+2[/tex]
[tex]40=-3x-10+2[/tex]
[tex]40=-3x-8[/tex]
Adding 8 on both sides
[tex]48=-3x[/tex]
Dividing both sides by -3
[tex]x=-16[/tex]
