Answer:
21
Step-by-step explanation:
Write the information out
y = 18
x = 2/3 *y
To find the value of 2x - 3, we first have to find the value of x
____________________________________________________________
Find the x
x = 2/3 x 18
x = (18/3) x 2
x = 6 x 2
x = 12
____________________________________________________________
Now we just replace 12 with x and solve
(2 x 12) - 3
= 24 - 3
= 21
