∙ 11y ago120 + 60 = 180
Y=30
Add the two equations you get 5y = 60 so y = 12 and x = 2
-60
60 + 60 + 120 = 240
75 + 45 = 120 = 60 + 60 two minutes
The result of the equation - 120 plus 90 plus 60 plus 80, is found as follows; 120 + 90 + 60 + 80 = ( 120 + 90 ) + 60 + 80 = 210 + ( 60 + 80 ) = 210 + 140 = 350 Answer = 350
Yes. 60 + 60 ------ 120
60 x 2 = 120
300 !
Divide both sides by -5: so y = -12
4x-5y=20 x-3y=10 becomes x=3y-10 plug that into the first equation: 4(3y-10)-5y=20 12y-40-5y=20 7y=60 y=60/7 If x=3y-10, then x=3(60/7)-10 x=180/7 - 70/7 x=110/7
