6 times the sum of a number and 8 equals 3

Answer 1

Let's represent the unknown number with the variable x.

Then the "sum of a number and 8" can be written as: (x + 8)

Next "6 times the sum of a number and 8" can be written as: 6(x +8)

Lastly "equals 3" can be written as : = 3

Combining these expressions gives us: 6(x +8) = 3

You can solve this equation to find the unknown number x using the distributive property and inverse operations:

6(x +8) = 3

6x + 48 = 3

6x + 48 - 48 = 3 - 48

6x = -45

6x/6 = -45/6

x = -7.5
