Question

Given the following linear equations:
2x+3y=10

4x-6y=-28

Solve for (x,y) if there is a solution

Answer 1

Mutiply the first equation by 2 and add it to the second to get
8x=-8
x=-1

-2+3y=10
3y=12
y=4

(-1,4)

Answer 2

its very simple

Answer 3

Multiply the first equation by 2 and add it to the second equation to get
8x=-8
Therefore x=-1

3y=10-2x = 10-2(-1) = 10+2 = 12

Therefore y = 12 / 3 = 4

(-1,4)
