A.) 2a + 11 = 33
Subtract 11 from both sides.
2a+11−11=33−11
2a=22
Divide both sides by 2.
2a/2=22/2
a=11 <-- Answer
B.) 3h + 7 = 23 - h
Step 1: Simplify both sides of the equation.
3h+7=23−h
Simplify
3h+7=−h+23
Add h to both sides.
3h+7+h=−h+23+h
4h+7=23
Subtract 7 from both sides.
4h+7−7=23−7
4h=16
Divide both sides by 4.
4h4=164
h=4
