Question

2x+3y=15
x+y=6
work out the value of x and y

Answer 1

I would use elimination
Multiply second equation by 2
2x + 2y = 12
2x + 3y = 15
Subtract both
-1y = -3, y = 3
Plug in 3 for y in any equation
x + 3 = 6, x = 3
Final answer: x = 3, y = 3

Answer 2

Answer: x=3, y-3

Step-by-step explanation:

I would use elimination

Multiply second equation by 2

2x + 2y = 12

2x + 3y = 15

Subtract both

-1y = -3, y = 3

Plug in 3 for y in any equation

x + 3 = 6, x = 3

Final answer: x = 3, y = 3
