What is the greatest common factor of 35 and 20

Hope this will help u....

5

Step-by-step explanation:

The greatest common factor is what is the biggest number that both numbers can be divided by

factors of 35= 1, 5, 7, 35

factors of 20= 1, 2, 4, 5, 10, 20

5 is the biggest number they both have in common

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
