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
