Can someone tell me the answers plz and how to do it DONT use photomath plz I’ll give brainlist and points don’t ignore?

Im  assuming you need both 18. x =3 20. No Solution

Step-by-step explanation:

8x-6-8=4+2x

Combine like terms

8x -14 = 4 +2x

Opposite of 14 so you can move it to the right

8x= 18 +2x

Subtract the x on the right side what you do to the right you do to the left

6x=18

Simplify

X=3

24a-22=-4+24a

Get rid of the number on the left do the opposite of negative so add 22 you get a positive 22 for the right side

24a=18+24a

Doesn't work so i guess the answer is No solution

step-by-step explanation:

should you really be posting this isn't math boi.

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
