Answer: you could buy 12 magazines
Step-by-step explanation:
each magazine is $2
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
Answer: it’s b
Step-by-step explanation:
60+95=155. 50+70=120. 155-35=120
X/35 = 100...multiply both sides by 35
x = 100 * 35
x = 3500
