WebSolve this one: x + 5 = 12 What we want is an answer like "x = ...", but the +5 is in the way of that! We can cancel out the +5 with a −5 (because 5−5=0) So, let us have a go at subtracting 5 from both sides: x + 5 −5 = 12 −5 A little arithmetic (5−5 = 0 and 12−5 = 7) becomes: x + 0 = 7 Which is just: x = 7 Solved! (Quick Check: 7+5=12) WebSteps to Solve an Equation (Math 119) 1. Does the equation contain fractions? If no, skip to step 3.
