DONT UNDERSTAND HOW TO DO 2-STEP EQUATIONS

Question

6+3b=-18

Answer 1

you want to get all the numbers on the right side by adding the opposite of what is on the left side, to both sides:

6 + -6 +3b =-18 +-6

3b =-24 after simplifying the numbers on both sides

now make the coefficient of the variable "1" by multiplying both sides by the reciprocal of the coefficient that is there:

3(1/3)b =-24(1/3)

b=-8
