Question

solve system y=x+2 and y=-4x+12

Answer 1

5x=10... get the ans

Answer 2

Hi
The first step is to make them equal to each other. This is because y =y.
Therefore set out as
x + 2 = -4x +12
gather like terms
Get all the x to one side, and then numbers to the other
x + 2 = -4x +12
x+4x +2 = +4x +12
5x +2 =12
5x -2 = 12 - 2
5x = 10
solve for x by dividing by 5,
x = 2
Now sub in this x value we have found into the original equation
x + 2 = -4x +12
2 + 2 = -4(2) +12
4 = -8 +12
4 = 4
y=y
y = 4
Hope it helps let me know good luck
