Hey Starr 10x - 5y = 20 20x + 5y = 20 Add them vertically 30x = 40 Are you with me so far?

OpenStudy (cggurumanjunath):

ADD BOTH THE EQ .

OpenStudy (anonymous):

Sorry I messed up. 30x = 120 right

OpenStudy (anonymous):

yes which x would equal 40

OpenStudy (cggurumanjunath):

OpenStudy (cggurumanjunath):

X=40

OpenStudy (anonymous):

x = 4 actually. Divide each side by 30 x = 4

OpenStudy (anonymous):

ok so 30 x 4 =120/30=4

OpenStudy (anonymous):

Correct :)
