x=2
Step-by-step explanation:
Quotient means division
20/(x+3) =4
Multiply each side by (x+3)
(x+3)*20/(x+3) =4(x+3)
20 = 4(x+3)
Divide each side by 4
20/4 = 4(x+3)/4
5 = x+3
Subtract 3 from each side
5-3 = x+3-3
2 =x

2+9-18/3x2-10
Lets follow order of ops.
/, x, +, -
Divide first.
2 + 9 - (18/3) x 2 - 10
2+9-6x2-10
Now we multiply.
2+9-(6x2)-10
2+9-12-10
Add.
11-22
Now subtract.
11-22=-11
