Solve the equation I will give ​

All real numbers, or No solutions

Step-by-step explanation:

okay, the equation says 4(x+4)=(4x+16)

if we apply 4 to the parenthesis we get 4*(x+4)=4x+16

so basically the equation is telling us 4x+16=4x+16, which gives us all real numbers or No solutions as the answer

4x+16=4x+16

Step-by-step explanation:

4(x+4)=(4x+16)

4x+16=4x+16

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
