x=5-6x can be solved by adding 6x to both sides 7x=5 is the result.
Now divide divide by 9 and
we have x=5/7 which is the solution.
This is a linear equation in 1 variable.
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94

The solutions to the quadratic equation are: x = -1 and x = 6
y = 5x - 4 Substitute 6 in for y; then solve for x: 6 = 5x -4 10 = 5x 2 = x So, the x-coordinate is 2.
