Question

What is the y-value

Answer 1

The given set of equations are,

`\begin{gathered} y=x+4\ldots..(1) \\ y=(3)/(2)x+10\ldots..(2) \end{gathered}`

Substituting the value of y from equation 1 in 2, we get,

`\begin{gathered} x+4=(3)/(2)x+10 \\ 2x+8=3x+20 \\ 2x-3x=20-8 \\ -x=12 \\ x=-12 \end{gathered}`

Now, substituting the value of x in equation 1. we get,

`y=-12+4=-8`

First option is correct
