Solve the system by the elimination method. Check your work. 2a + 3b = 6 5a + 2b - 4 = 0

1 answer:

4 0

Solve the system by the elimination method.
2a + 3b = 6
5a + 2b - 4 = 0

multiply thru the top equation by 2
Multiply thru the bottom equation by 3

4a + 6b = 12
15a+ 6b = 12

Subtract and solve for "a":
11a = 0
a = 0

Solve for "b" using 2a + 3b = 6
2*0 + 3b = 6
b = 2
