How can x + 2 = −3x + 11 be set up as a system of equations? y = x + 13 y = −3x + 11 y = x + 2 y = −3x + 11 y = x + 2 y = −2x + 11 y = 2 y = −3x + 11

Anything of the form A = B can be broken into y = A and y = B as one system of equations. 

So x+2 = -3x+11 breaks down into the system shown below

y = x+2
y = -3x+11

Choice B

Number 5 is 50 degreesnumber 6 is 45 degreesnumber 7 is 60 degreesnumber 8 is 45 degrees
