Best Answer

x + y = 6

2x + y = 8

Subtract the top equation from the bottom one:

2x - x + y - y = 8 - 6

x = 2

Going to the top equation, substituting 2 for x:

2 + y = 6

Which you should be able to solve if you are asking this question.

Q: What is the solution to x plus y equals 6 and 2x plus Y equals 8?

5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2

The solution is (x, y, z) = (2.5, 1, 2.5).

The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2

x = 0 & y = -3

Solution: 2x + 6 = 2 2x = -4 x = -2 Check: LHS = 2*(-2) + 6 = -4 + 6 = 2 = RHS

X = 6

The solution is (x, y, z) = (2.5, 1, 2.5).

If: y = x+6 and y = 2x Then: x+6 = 2x And: 6 = 2x-x => 6 = x So: x = 6 and y = 12

The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
