Question

y=2x-12
y=4x-16

Answer 1

what do u need done?

Answer 2

subsitution

Answer 3

I suppose yo uwant to solve for x and y?

Answer 4

x=2

Answer 5

oh yea... never been good at that!! they can prolly help u better im pro at elimination just not substitution... ^ ^

Answer 6

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)

Answer 7

2x-12=4x-16.....combine like terms

Answer 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

Answer 9

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
