A two-step equation, such as 2x + 3 = 9, has two different operations, multiplication and addition. To solve a two-step equation, undo the operations in reverse order of the order of operations.
True or False
2x + 3 = 9 -3 = -3 2x = 6 2x ÷ 2 = 6 ÷ 2
x = 3x ÷ 3 = 3x = 9 3x + 1 = 10
x = ÷ 3 x/3+12=8 Solve. 2x+6<12 Solve. x/2+6=10 Solve. 4=16+6y Solve. 4y-9<11 Solve. Mary is saving money to buy a bike that costs $195. She has saved $95 so far. She plans on saving $10 each week.
