-2 multiplied by 3x = -6x
-2 multiplied by 7 = -14
so -6x-14=32-4x
move -6x to the other side
= -14= 32-4x+6x
simplify
=-14=32+2x
move 32 to the other side
= -14-32=2x
simplify
=-46=2x
divide
-46/2 = 2x/2
x = -23
14)NO..... -2x+5y=10.....-2(-3)+5(2)=10.....6+10 is not =10
15)YES......-2x+5y=10....-2(-10)+5(-2)=10.....20-10=10
16)YES......-2x+5y=10.....-2(5)+5(4)=10......-10+20=10

so rise would be money, run would be number of puppies adopted
Answer:
x = 15
Step-by-step explanation:
given that y varies directly with x
mathematically we can express this as
y = k x , where k is a constant
step 1: find k
given x = 3 and y = 21
y = k x
21 = k (3)
k = 7
hence the equation becomes
y = 7 x
when y = 105,
105 = 7x
x = 105 / 7 = 15
