Question

Y = x + 1 and y = -1/2 x +4 what is the solution

Answer 1

Y=x+1
y=-1/2x+4
y=y
x+1=-1/2x+4
1x+1/2x+1=4
3/2x=4-1
3/2x=3
x=3/(3/2)
x=2

Answer 2

x+1 = -1/2x+4

subtract x from both sides

1=-1 1/2x +4

subtract 4 from each side

-3 = - 1 1/2x

divide both sides by -1 1/2

x= 2

check the answer:

2+1 =3

-1/2(2) +4 = 3

 so X = 2
