Question

Two times the quantity of eight times a number plus two is equal to three the quantity of two times the same number minus seven

Answer 1

The unknown number is - 2.5

Let the number = n

The equation will be formed as follows;

• eight times a number plus two = 8n + 2

• Two times the quantity of eight times a number plus two = 2(8n + 2)
• two times the same number minus seven = 2n - 7
• three the quantity of two times the same number minus seven = 3(2n-7)

Our final equation becomes;

2(8n + 2) = 3(2n-7)

Simplify as follow, to determine the unknown number;

16n + 4 = 6n - 21

16n - 6n = -25

10n = -25

n = -2.5

Thus, the unknown number is - 2.5
