21x+3=121 Subtract 3 from both sides

21x+3=121

Add -3 to each side:
21x+3-3=121-3
21x = 118

Divide both sides by 21:
%2821x%29%2F21=118%2F21
x=+118%2F21

What an UGLY answer! Life doesn't always come out even, does it? In this case, the fraction doesn't even reduce!! How sad!!

Subtracting 3 on both sides
21x +3 -3 = 121 - 3
21x = 118
Dividing by 21 throughout
X = 118/21
