x/3 = y/5 and 3 + y = z
Which of the following equations , together with the two equations above, will form a system of three equations such that there is only one value of x that satisfies all three equations?
a.) z + y = 5
b.) y = z -3
c.) 5x = 3y
d.) z-y = 3
e.) x = 3/5y
Should i solve each equation and go through the ones it can't be?
