Tomas wrote the equation y = 3x +y equals 3 x plus StartFraction 3 over 4 EndFraction.. When Sandra wrote her equation, they discovered that her equation had all the same solutions as Tomas’s equation. Which equation could be Sandra’s?

–6x + y = negative 6 x plus y equals StartFraction 3 over 2 EndFraction.
6x + y = 6 x plus y equals StartFraction 3 over 2 EndFraction.
–6x + 2y = negative 6 x plus 2 y equals StartFraction 3 over 2 EndFraction.
6x + 2y = 6 x plus 2 y equals StartFraction 3 over 2 EndFraction.

Start with Tomas’s equation: y = 3x + 3/4.
Subtract 3x: y − 3x = 3/4, i.e. −3x + y = 3/4.
Multiply both sides by 2: −6x + 2y = 3/2.

So Sandra’s equation could be −6x + 2y = 3/2.
