First you would add any numbers or variables (x) on each sides. So the equation would look like this -5h+12=32. Then you subtract 12 from both side because you are trying to find what H is; thus making the equation look like this, -5h=20. Then you can divide by -5 and the answer would be h=-4. You can plug it back into the equation to make sure it is correct. 10-5(-4)+2=32 10+20+2=32 32=32 It works.
