Solve the equation 2y + 3 = -11

 =  − 7

Step-by-step explanation:

y= -7

Step-by-step explanation:

move the constant to the right and change the sign

2y=-11-3

2y=-14

divide both sides by two

y=-7

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

answer: b
