-1-2x-4x=19-6x-1 = -19x = 3

3x-2 = 2x+3 3x-2x = 3+2 x = 5

Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x

-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x

To solve this, present the equation in the standard slope/intercept form of y = mx + c. 'm' is the slope. 2x + 5y = 10 5y = -2x + 10 y = -2/5x + 2 Therefore, -2/5 is the slope.

To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)

You cant solve it unless it is an equation. To be an equation it must have an equals sign.

y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)

Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4

2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9
