What is X plus 3y equals 2 and 2x - 3y equals 22?

Answer 1

Simple system.

X + 3Y = 2

2X - 3Y = 22

------------------------add

3X = 24

X = 8

--------------------now, insert back into one of the equations to find Y

8 + 3Y = 2

3Y = - 6

Y = - 2

----------------check both equations

8 + 3(- 2) = 2

2 = 2

---------------top checks

2(8) - 3(- 2) = 22

16 + 6 = 22

22 = 22

----------------both are consistent, so

X = 8

Y = - 2
