Question

Please can you work out this question ?

Answer 1

Step-by-step explanation:

→ 16 = 8(x + 9)

→ 16 = 8x + 72

→ 8x = 72 - 16

→ -8x = 56

→ x = 56/-8

→ x = -7

therefore, value of x is -7.

hope this answer helps you dear!

Answer 2

Step-by-step explanation:

Simplifying

16 = 8(x + 9)

Reorder the terms:

16 = 8(9 + x)

16 = (9 * 8 + x * 8)

16 = (72 + 8x)

Solving

16 = 72 + 8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8x' to each side of the equation.

16 + -8x = 72 + 8x + -8x

Combine like terms: 8x + -8x = 0

16 + -8x = 72 + 0

16 + -8x = 72

Add '-16' to each side of the equation.

16 + -16 + -8x = 72 + -16

Combine like terms: 16 + -16 = 0

0 + -8x = 72 + -16

-8x = 72 + -16

Combine like terms: 72 + -16 = 56

-8x = 56

Divide each side by '-8'.

x = -7

Simplifying

x = -7
