Question

Solve the system
2x + y=24
3x + y=16

Answer 1

(- 8, 40 )

Explanation:

Given the 2 equations

2x + y = 24 → (1)

3x + y = 16 → (2)

Subtract (1) from (2) term by term to eliminate the y- ter, that is

x = - 8

Substitute x = - 8 into either of the 2 equations and solve for y

Substituting into (1)

2(- 8) + y = 24

- 16 + y = 24 ( add 16 to both sides )

y = 40

solution is (- 8, 40 )

Answer 2

point form (-8,40)

equation form x=-8, y=40
