So you have the equation (2x+4)/-3=12
Multiply by -3 on each side.
2x+4=-36
2x=-20
x=-10
Hope this helps.
We will use distribution
we will multiply 6 to each variable and number in the parenthesis.
6 times x plus 6 times 4
which is 6x +24
Since the 50 remains the same every time, is has no letters next to it in the equation. The 20, however, is multiplied by the amount of hours, and will therefore have an h next to.
20h + 50- the answer is a.
