TWO STEP EQUATIONS WITH FRACTIONS
Solving
Usually with 2-step equations, we have to use an inverse operation to solve the problem. First, isolate the variable and then solve from there.
Example using multiplication
8+m/4=17
-8 -8
M/4=9
M/4*4=4*9
M=36
Step 1: isolate the variable by subtracting 8 from each side.
Step 2: now, m/4=9, so we have to multiply m/4 and 9 by 4.
Step 3: m/4 is canceled into m from multiplying m/4*4, and 9*4 is 36, so m=36.
Example using division
12/a-7=-1
Step 1: isolate the variable by adding 7 to both sides
Step 2: you now have 12/a=6, and so you divide 12 by 6
your answer is a=2
