Solving equations with variables on both sides A continuation
Follow the checklist: 1.) Combine all like terms on each side. 3x+2x+5=6+7-2x+x would become____________ 2.) Add or subtract the smaller number in front of a variable to both sides. Hint(no sign and plus sign mean subtract to both sides, minus sign or negative sign means add to both sides) 5x+5 = 13-x 3.) Code or solve as you normally would.
Rearranging: If an equation looks like 3-x = -4, switch to –x + 3 = -4 and code from there. You try: 2 – 3y = 12 11 – m = 12 10 – p = 22 ½ - k = 20
Practice: 1.) 3x + 2x + 3 = 10 – 4x 2.) 10 – x = 2(x+3) 3.) –(x – 3) = 15 + 2x
