Solve : 3 ( 5m -7 ) -6m = -66
3 ( 5m -7 ) -6m = -66
15m - 21 - 6m = -66
9m - 21 = -66
+21 +21
9m = -45
m = -5
Write inequality:
Nancy has $240 in the vank. She wants to buy as many $15 video games as possible. How many video games could she buy if she wanted to keep at least $120 in the bank.
240 - 15x ≥ 120
Looking at the problem : -15a - 110 + 7a = 90
What is your first step?
Combine like terms ( -15a and 7a)
Solve: (r - 27)/ -4 ≤ -6
