Answer:
y=8
Step-by-step explanation:
Add 12y to both sides
7y+6=62
Minus 6 from both sides
7y=56
Divide by 7 on both sides
y=8
Y equals 8
2a + 3b = 6
5a + 2b = 4
We multiply the first equation by 5 and the second by 2 and and subtract the second from the first:
10a + 15b = 30
-10a -4b = -8
11b = 22
b = 2
2a + 3(2) = 6
2a = 0
a = 0
Checking,
5(0) + 2(2) = 4
4 = 4, true
