y=84-72=12 z=84-52=32 x=84-12-32=40
134
Given y = 2x + 4, plug in x = 42 and simplify: y = 2(42) + 4 y = 84 + 4 y = 88
78
x = 6y = 89x + 10y = 9(6) + 10(8) = 54 + 80 = 134
lets call the one number X and the other Y so y equals 3X so 3X plus X equals 84 so 4X equals 84 we divide by 4 so x equals 21 so y equals 21 times 3 equals 63 so the two numbers are 63 and 21
4y
-35y-134 = -29 -35y = 134-29 -35y = 105 y = -3
a = 3 and y = 0
x = y = 0 ?
84
-17 + y,,must be equals to..-17y..
