Answer:

A. x = 17/2

Step-by-step explanation:

2x+3=20

to find the value of x, isolate the variable!

1. Subtract 3 from each side of the equation

2x + 3 - 3 = 20 - 3

[+3-3 is 0 so we can take that out; 20-3=17]

2x = 17

2. Divide each side by 2

2x/2 = 17/2

[2x/2 = 2/2*x = 1*x = x]

x = 17/2
