Answer:
[tex]-6x+2y=\frac{3}{2}[/tex]
Step-by-step explanation:
The equation Thomas wrote is:
[tex]y=3x+\frac{3}{4}[/tex] ...equation 1
Let us subtract 3x from both sides to get:
[tex]-3x+y=\frac{3}{4}[/tex]
We now multiply through by 2 to get:
[tex]-6x+2y=\frac{3}{2}[/tex] ....equation 2
We can see that equation one and two are equivalent and hence have the same solution.
Therefore Sandra's equation is [tex]-6x+2y=\frac{3}{2}[/tex]
