Solve for x.
4 - 3x
2
= 5
A) -2
B) -1
2

C) 1
2

D) 2

A) -2

Step-by-step explanation:

4 - 3 x 2 = 5

4 - 6 = 5

-2 does not =  5 therefore the answers is A.

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

the first one
