Which equations are in standard form? Check all that apply

y = 2x + 5
2x + 3y = –6
–4x + 3y = 12
y = y equals StartFraction 3 Over 2 EndFraction x minus 9.x – 9
StartFraction one-half EndFraction x plus 3 equals 6.x + 3 = 6
x – y = 5
5x + 3y = 5 x plus 3 y equals StartFraction one-half EndFraction.

1 answer

2x + 3y = –6
–4x + 3y = 12
x – y = 5
