Answer:

Explanation:

5x – 4y = -10

y = 2 x – 5

Rearrage the equation:

5x – 4y = -10 (1)

-2 x +y = 5. (2)

pluging variable y equation2 in 1

5x - 4•(2x-5) = -10

-3x = -30

Solve equation [1] for the variable x

3x = 30

x = 10

x = 10

y = 2x-5

Use the x value to solve for y

y = 2(10)-5 = 15

x= 10

y= 15
