Use substitution to solve the linear system of equations. 2y = x-6 x= 9

2y = x-6, x=9
2y = 9-6; plug 9 in for x
2y = 3; evaluate 9-6
y = 3/2; divide each side by 2

x = 9
y = 3/2

Hope this helps!

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
