The solution to 5 − 3x > 35 is either x > -10 or - 10 > x.

x < -10

Step-by-step explanation:

5 − 3x > 35

Subtract 5 from each side

5-5 − 3x > 35-5

-3x > 30

Divide each side by -3, remembering to flip the inequality since we are dividing by a negative

-3x/-3 < 30/-3

x < -10

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
