Question

5. 40 = }(9x + 30) + 2

Answer 1

Answer:

x=-16

Step-by-step explanation:

We are given with the equation

$40=-\frac{1}{3} \times (9x+30)+2$

We are asked to solve it for x.

Distributing $\frac{1}{3}$ over bracket and simplifying

$40=-(\frac{9x}{3}+\frac{30}{3})+2$

$40=-(3x+10)+2$

$40=-3x-10+2$

$40=-3x-8$

Adding 8 on both sides

$48=-3x$

Dividing both sides by -3

$x=-16$
