-15 = y/7
(x both sides by 7)
-105 = y
neg 22 because a neg minus a neg u add them and make it negative
The sum of 7/15 and 5/12 equals 53/60
x=3 and y=4. you multiply x+y=7 by neg. 2 this way you can cancel out the y factors and get neg. 2x+x=-14+11 neg. x = neg. 3 divide both sides by neg. 1 to get x=3. use substitution to get y=4
3 over 5 is the same as 9 over 15 so x = 7 over 15.
2/5 plus 1/15 equals 6/15+1/15 equals 7/15.
22
7
8+7 = 15
2/5 + 3/7 = 14/35 + 15/35 = 29/35
2/5 + 3/7 = 14/35 + 15/35 = 29/35
105 divided by 7 will equal 15.
m/5 + 8 = -7 m/5 = -15 m = -15 x 5 m = -75
