Answer:

(5, -2)

Step-by-step explanation:

Use substitution

Y=5x-27 Put this equation into the place of y in the second one.

2x+3y=4

2x + 3(5x - 27) = 4     then solve for x

2x + 15x - 81 = 4

17x - 81 = 4

17x = 85

x = 5

Then put the value of x back into one of the equations and solve for y

y = 5(5) - 27

y = 25 - 27

y = -2
