Solve 4(x-5) = 18

Answer 1

9.5 or 19/2

Explanation:

4 ( x - 5 ) = 18

Step 1 : Divide 4 on both sides.

x - 5 = 18/4

x - 5 = 4.5

Step 2 : Add 5 on both sides.

x = 4.5 + 5

x = 9.5

Value of x in fraction = 95/10 = 19/2

Value of x in decimal = 9.5

Answer 2

x = 19/2 or 9.5

Explanation:

a) Distribute.

(4)(x) + (4)(−5) = 18

4x + −20 = 18

4x − 20 = 18

b) Add 20 to both sides.

4x − 20 + 20 = 18 + 20

4x = 38

c) Divide both sides by 4.

4x/4 = 38/4

x = 19/2 or 9.5
