Solving basic equations x + 14 = 34 - 14 = -14 x= 20 Step one: Subtract 14 from both sides. Step two: bring down the x x=20 Practice X + 16 = 24 X+24=63 x+34=84

Solving basic equations x - 20 = 34 +20 = +20 x= 54 Step one: Add 20 to both sides. Step two: bring down the x x=54 Practice X - 16 = 7 X-24=15 x-34=14

Solving basic 2 step equations 3x - 20 = 34 +20 = +20 3x= 54 3 3 Step one: Add 20 to both sides. Step two: bring down the 3x Step Three: divide both sides by 3 X= 18 Practice 4X + 16 =120 5X-25=10 4x-34=14

Practice: solving basic equations X + 45 = 127 3x + 9= 27 2x + 14= 28 2x + 45 = 122 4x-7=32 5x- 40= 125 3x-12= -15 -6x-12= 144 -4x+12=36
