Match each equation with the correct method to solve 1. -6y = 12 2. 12y = -6 3. y/-6 = 12 4. x+4 = -6 B. Divide both sides by -6 ? C. Divide both sides by 12 ? D. Subtract 4 from both sides ? A. Multiply both sides by -6 ? SOLVE EACH EQUATION, THEN CHECK. 5. K + 17 = 29 K = CHECK K + 17 = 29 + 17 = 29 = SOLVE EACH EQUATION, THEN CHECK. 6. h - 37 = -42 h = CHECKh - 37 = -42 - 37 = -42 = SOLVE EACH EQUATION, THEN CHECK. 7. z/8 = -3 z = CHECKz/8 = -3 /8 = -3 = SOLVE EACH EQUATION, THEN CHECK. 8. -7n = -56 n = -7 x CHECK-7n = -56 = -56 = 9. A student collects 12 ladybugs for a science project. This is 9 fewer than the number of ladybugs the student collected yesterday. Define a variable, write and solve an equation to find the number of ladybugs the student collected yesterday. Equation: Problem: = = Variable: 10. Nine weeks from now Susan hopes to buy a bicycle that costs $180. How much money must she save per week? Define a variable, write and solve an equation to find how much money she must save per week. Equation: Problem: = = Variable: SOLVE THE EQUATION. THEN CHECK 11. 5n - 18 = -33 5n = n = CHECK: 5n - 18 = -33 5 ( ) - 18 = -33 - 18 = -33 = SOLVE THE EQUATION. THEN CHECK 12. w/5 + 3 = 6 w/5 = w = CHECK: w/5 + 3 = 6 /5 + 3 = 6 + 3 = 6 = SOLVE THE EQUATION. THEN CHECK 13. 6(n - 2) = 6 n = 6n = = 6 6 CHECK: 6(n - 2) = 6 ( 6 x - 2) = 6 = 6 = 14. Whats the error? 1/2(b - 8) = 4 1/2b - 4 = 4 +4 +4 1/2b = 8 ÷2 ÷2 b = 4 Answer 15. In addition to her hourly rate, an electrician charges a fee to come to your house. This can be modeled by 40h + 35 = 115. Explain what each part of the equation represents. Then solve the equation to find the number of hours she works. 40h = Problem: = = 115 = 35 = 16.
