Answer:

x = 5

Explanation:

Represent the number with 'x.'

Rewrite the relationship symbolically: 8x + 10 = 50.

Now solve for x. Group like terms: 8x = 40. Divide both sides by 8: x = 5

Answer:

The number is 5

Explanation:

Let x be the number

product of a number and 8

8x

Increased by 10

8x+10

is 50

8x+10 = 50

Solve the equation

Subtract 10 from each side

8x+10-10 = 50-10

8x = 40

Divide each side by 8

8x/8 = 40/8

x = 5
