Answer:
7
Step-by-step explanation:
5x + 2y = 12
-6x - 2y = -14
Add them
-x = -2
x = 2
5x + 2y = 12
(5*2) + 2y = 12
10 + 2y = 12
2y = 2
y = 1
Answer:
y=1.5x
78
Step-by-step explanation:
y=1.5x
y=1.5(52)
y=78
Answer:
If both numbers have to stay equivalent, then y equals 30 if x = 12. My reasoning is 12/4 = 3. 3 times 10 = 30.
