Question

4х + бу = 10
—10x + 2y = – 8
what’s the point

Answer 1

x = 1

y = 1

(1, 1)

Explanation:

simplify each equation first:

`4x + 6y = 10\\2x + 3y = 5`

and

`-10x + 2y = -8\\-5x + y = -4`

The you would have:

2x + 3y = 5

-5x + y = -4

Multiply both sides of the second equation by 3

`-15x + 3y = -12`

Subtract the two equations:

17x = 17

divide both sides by 17

x = 1

substitute this in:

2 + 3y = 5

3y = 3

y = 1
