Answer:

X = 12

Step-by-step explanation:

When a number increased by 4

Let that number = x

x + 4

is doubled...

2(x + 4)

the result is the same

=

when the number is increased by 20

x + 20

Find the number

2 (x + 4) = x + 20

2x + 8 = x + 20

2x - x = 20 - 8

x = 12

What does X equal? X equals 12

Check:

Insert the x = 12 into the equation;

2 (x + 4) = x + 20

2 (12 + 4) = 12 + 20

2 (16) = 12 + 20

32 = 32
