Answer: 10-8 + h = -8 + 18 = 10 5. If d = 22 then d − 10 = _______
Answer: 12d − 10 = 22 − 10 = 12 6. If y = 13 then y − 5 = _______
Answer: 8y − 5 = 13 − 5 = 8 7. If r = 9 then -r + 19 = _______
Answer: 10-r + 19 = -9 + 19 = 10 8. If a = 9 then -10 + a + 5 = _______
Answer: 4-10 + a + 5 = -10 + 9 + 5 = 4 9. If g = 7 then -11 − g + 4 = _______
Answer: -14-11 − g + 4 = -11 − 7 + 4 = -14 10. If q = -19 then q −12 + 8 = _______
Answer: -23q −12 + 8 = -19 − 12 + 8 = -23 11. If p = 7 then p × -5 = _______
Answer: -35p × -5 = 7 × -5 = -35 12. If b = -4 then b × 7 = _______
Answer: -28b × 7 = -4 × 7 = -28 13. If z = 5 then 9 × -z = _______
