Triple the sum of a number and 7 is the same as 8 more than the number

we can determine the value of this number by setting an equation

the sum of the number and 7, multiplied by 3, is equal to 8 plus the number.

making x= the unknown number, we can say:

3(x+7) = 8 + x

now we can distribute the 3 and solve for x

3x+21 = 8+x

2x+21=8

2x= -13

x = -6.5

hope this helped
