Solve for the unknown variable: -8m - 9 = 39
Lemur [1.5K]

Answer:

m =-6

Step-by-step explanation:

To solve for the unknown variable, m, we have to get m by itself. Perform the opposite of what is being done to the equation.

-8m-9=39

9 is being subtracted from-8m, so add 9 to both sides. Addition is the opposite of subtraction.

-8m-9+9=39+9

-8m=39+9

-8m=48

-8 and m are being multiplied. Divide both sides by -8, because division is the opposite of multiplication

-8m/-8=48/-8

m=48/-8

m= -6
