In this activity, you will practice solving: Practice Solving Equations * one step equations * two step equations * multi step equations * equations with variables on both sides One way to solve equations is by using INVERSE OPERATIONS. The inverse of addition is The inverse of subtraction is The inverse of multiplication is The inverse of division is subtraction ? multiplication ? addition ? division ? Example 1: One step equation 4x = -12 4 4 x = divide both sides by 4 solution Example 2: Solving two step equations 2p = -24 2p - 3 = -27 2 p = + 3 +3 2 divide both sides by 2 add 3 to both sides solution Your turn! Solve the one step equation. Fill in the missing numbers. 5y = -5 y = Your turn! Solve the two step equation. Fill in the missing numbers and operations. 3y + 8 = 23 3y = 15 y = Solve the two step equation by using inverse operations -4y - 1 = 15 -4y = 16 y = Solve the equation with the variable on the right side. 51 = 4x + 3 = 4x = x Solve the multi step equation. -20 = 5n + -20 = 5(n + 2) = n = 5n + 10 Solve the equation with variables on both sides. + 5x + 5x -3x + 14 = -5x + 6 + 14 = - 14 x = = -8 Solve this multi step equation. 3(2x - 1) - 2x = 21 6x - - 2x = 21 - 3 = 21 x = = Divide both sides by 4 Distribute the "3" Combine like terms Add 3 to both sides Solve the multi step equation. + 4x + 4x -2x = -4x -2(x + 9) = -4(x - 1) - 18 = 4 2x = x = |
