Question

solve x-2 Y = -7 and 4 x + 3 Y= 5

Answer 1

x = -2

y = -7

4 * (-2) + 3 * (-7) = -8 + (-21) = -29

Answer 2

Step-by-step explanation:

x-2y = -7........ (1)

4x +3y = 5......(2)

multiply (1) by 4

4x -8y = -28......(3)

Let's solve (2)&(3)

4x -8y = -28

4x +3y = 5

- - -

___________

0 -11y = -33

y = 3

put y = 3 in (2)

4x +3y = 5

4x +3(3) = 5

4x = -4

x = -1

So (x,y) = (3,-1)

Hope it helps uh!!!!!
