1/2(b + 2) + 3b = -1

what is the value for b ?

b= -1

Step-by-step explanation:

1/2(b+2) + 3b = -1

b/2 + 1 + 3b = -1

b/2+3b =-2

b+3b=-4

4b=-4

b=-1

yes

step-by-step explanation:

give me the question

\

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
