Answer:
(-2, 3) , 2nd has no answer
Step-by-step explanation:
5x + 6y = 8 and 2x + 3y = 5
Multiply the second x 2 so they both have 6y
5x + 6y = 8
4x + 6y = 10 Now subtract
x = -2 Put -2 in for x:
2(-2) + 3y = 5
-4 + 3y = 5
3y = 9
y = 3
Second problem:
4y = 12x + 3 and y = 3x + 1
Substitute the second equation into the first
4(3x + 1) = 12x + 3
12x + 4 = 12 x + 3
4 = 3
There is no answer
