Answer: x = 1, y = 4

Steps: 3y + 4x = 16, -2x + y = 2

Isolate y for 3y + 4x = 16: y = (16 - 4x ÷ 3)

Substitute y into the other equation (-2x + y = 2): -2x + (16 - 4x ÷ 3) = 2

Simplify: 16 - 10x ÷ 3 = 2

Isolate x for 16 - 10x ÷ 3 = 2: x = 1

Substitute x = 1 into y = (16 - 4x ÷ 3): y = 16 - 4x · 1 ÷ 3

y = 4, x = 1
