Question

Solve. 12.6-0.4h+2.5-0.5=15-0.9h-7.1

Answer 1

12.6+2.5-.5=14.6
15-7.1=7.9
so simply you get
14.6-.4h=7.9-.9h
so now you need to get like terms together so bring the number with the variable h to the left of equal sign and whole # 14.6 to right:
add .9h to both sides and substract 14.6 from both side of equal sign
.9h-.4h=-14.6+7.9
.5h=-6.7
divide by .5
h=-6.7/.5
