Since the highest power of 'x' in the equation is '1', there's one solution.

8x - 6y = 184x - 6y = 6from the first equation:6y = 8x - 18substitute this value in the second equation:4x - (8x - 18) = 64x - 8x + 18 = 6-4x = 6 - 18-4x = -12x = 3Solve for y :8 x 3 - 6y = 1824 - 6y = 186y = 6y = 1

It is a linear equation in one variable r. The solution to the equation is r = 1.

7+8x-5 = 8x+7-5x Subtract 7 from both sides: 8x-5 = 8x-5x Subtract 8x from both sides: -5 = -5x Divide both sides by -5: x = 1 So the equation implies x = 1

This is a linear equation. The value x = -1 is the solution to this equation.

No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a solution.

x - 8x = 1 Perform the indicated subtraction on the left side: -7x = 1 Divide each side of the equation by -7 : x = - 1/7

Since the highest power of 'x' in the equation is '1', there's one solution.

x=1, y=1

8x - 8y = 1Add 8y to each side:8x = 8y + 1Subtract 1 from each side:8x - 1 = 8yDivide each side by 8:y = x - (1/8)

8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4

-8x = 32Divide each side by 8:-x = 4Multiply each side by -1:x = -4

(4 ± i2) where i2 = -1

There is only one equation that is given in the question and that equation is not a direct variation.

It would be perpendicular to a line with the equation Y = 1/8 X.

8x - 6y = 184x - 6y = 6from the first equation:6y = 8x - 18substitute this value in the second equation:4x - (8x - 18) = 64x - 8x + 18 = 6-4x = 6 - 18-4x = -12x = 3Solve for y :8 x 3 - 6y = 1824 - 6y = 186y = 6y = 1

Same way you graph y = -4x - 0.5
