Twice the sum of 18 and x is 42

Mathematics
1 answer:
nydimaria [60]3 years ago

Answer:

x=3

Step-by-step explanation:

We are taking 2 times the sum ( addition) of 18 and x

2 ( 18+x) = 42

Divide each side by 2

2 /2 ( 18+x) = 42/2

18+x = 21

Subtract 18 from each side

18+x-18 = 21-18

x = 3
