Answer:

x = 1

y = 1

(1, 1)

Step-by-step explanation:

simplify each equation first:

[tex]4x + 6y = 10\\2x + 3y = 5[/tex]

and

[tex]-10x + 2y = -8\\-5x + y = -4[/tex]

The you would have:

2x + 3y = 5

-5x + y = -4

Multiply both sides of the second equation by 3

[tex]-15x + 3y = -12[/tex]

Subtract the two equations:

17x = 17

divide both sides by 17

x = 1

substitute this in:

2 + 3y = 5

3y = 3

y = 1
