OpenStudy (gentorr):

is this a multiple choice question

OpenStudy (gentorr):

?

OpenStudy (gentorr):

ohh okay

OpenStudy (jameshorton):

first one y = 4x – 2

OpenStudy (jameshorton):

2x + y = 9 3x – y = 16

OpenStudy (jameshorton):

Note that, if I add down, the y's will cancel out. So I'll draw an "equals" bar under the system, and add down: 2x + y = 9 3x – y = 16 5x = 25
