Seven less than the product of 2 and a number is equal to 8.

use the variable w for the unknown number .

➷ We can use that statement to form an equation:

2w - 7 = 8

Now we need to solve for w

Add 7 to both sides:

2w = 15

Divide both sides by 2:

w = 7.5

15/2

Step-by-step explanation:

"7 less than the product of 2 and a number" comes out to 2w - 7.

This quantity equals 8:

2w - 7 = 8.

Adding 7 to both sides isolates 2w:

2w = 15

Dividing both sides by 2 yields

w = 15/2

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
