Y=x-3
y=42x + 1
NEED HELP ASAP

y=1

x=4

Step-by-step explanation:

Since we know that y=x-3 and y=1/2x+1  we know that 1/2x+1= x-3

so know we can just simplify and evaluate the equation like this:

x-3= 1/2x +1

-1/2      -1/2

1/2x-3=-1

      +3  +3

1/2x=2

x=4  

now lets subsititute

y=4-3

y=1

 Hope it helps tell me if it's wrong in the comments.

so what is the question

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
