Eight more than four times a number is -12

Answer 1

To solve problems like these it is is often easiest to set up an equation.

in the problem "a number" is the unknown value so it our equation it will be represented a "x"

the problem first specifies that we are going to add 8 the our unknown number so our equation become

x + 8

Next, the problem specifies that it we will be adding 8 to 4 time our number so our equation becomes

4x + 8

Finally, the problem states that our answer will be equal to -12 so our answer becomes

4x + 8 = -12

It is also possible to take this problem a step further and solve for the unknown number or "x"

To do this we would start by subtracting 8 from both sides of the equal sign to isolate "x"

so our equation becomes

4x = -32

then we would divide each side of the equation by 4 and our final answer would be

x = -8
