Is x plus 2y equal 7 and 2x plus 4y equals 3 perpendicular?

No. They are parallel.

3y-x equals 0 and 2x plus 2y equals 7?

Multiply First equation by 2: 6y - 2x = 0Add second equation to this: 6y - 2x + 2x + 2y = 0 + 7Simplify: 8y = 7 so y = 0.875 and x = 2.625

What are the exact values of x and y when 3x plus 2y equals 5x plus 2y equals 7?

If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5

X plus 2y equals 4 y equals 2x plus 7 what does x and y equal to?

x = -2 and y = 3
