    set the two equations equal to each other: 2x - 12 = 4x - 16 solve for x: 4 = 2x thus x = 2 plug this into either equation to find y: y = 2(2) - 12 = 4 - 12 = -8 solution: (2, -8)

    if y = 2x-12 and y = 4x-16, then 2x-12 = 4x-16. solve for x. get y by substituting the value of x in one of the equations

    Since y =2x-12 and 4x-16, we can say that 2x-12=4x-16. Now, to solve for x we can add 16 to both sides of the equation. That gives us 2x+4=4x. Since we want x on one side of the equation and the constants on the other, we can subtract 2x from both sides. That gives 4=2x. Now divide both sides by 2 and you have x=2. to find y, substitute x into one of the original equations. y=2x-12. Y=2(2)-12=-8 so, x=2 and y=-8
