The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method

The given equation is $\frac{x}{3} + 8 = -2$

Solving the equation using Natasha's method

the fist step is to multiply by 2

x + 24 = - 6

The second step is to combine and add similar terms

x = -24 - 6

x = -30

Second method of solving the equation

The equation the friends are trying to solve is $\frac{x}{3} + 8 = -2$

The first step is to combine similar terms

$\frac{x}{3}$ = - 8 - 2

The second step is to add similar terms together

$\frac{x}{3}$ = - 10

The third step is to multiply both sides of the equation by 3

x = (-10 x 3)

x = -30
