Question

Solve the system of equations. 3x - 2y = 9 x + y = 8 (6, 2) (3, 0) (1, 6) (5, 3)

Answer 1

(5,3)

Explanation:

The given equations are;

`3x-2y=9...(1)`

`x+y=8...(2)`

Multiply equation (2) by 2

`2x+2y=16...(3)`

Add equation (3) and equation (1)

`3x+2x=9+16`

5x=25

x=5

Put x=5 into equation (2)

5+y=8

y=8-5=3

Hence the solution is

(5,3)
