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