The product of a number and 4 increased by 8 is negative 36

4x+8=36 would be the equation.

x · 4 + 8 = - 36

How to solve this problem:

x · 4 + 8 = - 36

The first step to getting x alone on one side is subtracting 8 from both sides:

x · 4 = - 36 - 8

x · 4 = - 44

Next we divide each side by 4:

x = - 44/4

x = - 11

Now lets substitute - 11 back into the original equation:

x · 4 + 8 = - 36

-11 · 4 + 8 = - 36
