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

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

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
