Question

X=2y-4, 5x-6y=-8 I need to solve this using the substitution method

Answer 1

x = 2

y = 3

Explanation:

x = 2y - 4

5x - 6y = -8

Substitute for x.

5(2y - 4) - 6y = -8

10y - 20 - 6y = -8

4y - 20 = -8

4y = -8 + 20

4y = 12

y = 12 ÷ 4

y = 3

x = 2y - 4

x = 2(3) - 4

x = 6 - 4

x = 2
