Find an equation of the plane that is parallel to the line of intersection of the planes ( x + 3y + z = 3 ) ( 3x - y - z = 0 ) and pass through the origin and point of intersection of the lines passes through the point of intersection of the lines ( x = ? = 2 + 2 ) and ( = y + 1 = 2 )

According to the data set, where should the upper quartile line of the box plot be placed?

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
