Question 76460: 2x+3y=40 and 2x+2y=20?
Answer by chitra(359)  (Show Source):
You can put this solution on YOUR website! The given equations are:
2x + 3y = 40 -----------(1)
2x + 2y = 20 -----------(2)
Subtracting EQN (1) from (2), we get:
y = 20
Substituing this in any one of the equations, we get:
2x + 2(20) = 20
2x + 40 = 20
2x = 20 - 40
2x = -20
x = - 20/2
x = -10
Hence, the values of x = -10 and y = 20 satisfies both of the equations.
Hence, the solution.
