The sum of 8 times a number and 7 equals 3.

8x + 7 = 3 (x = -0.5)

Step-by-step explanation:

I think this is the equation for what you said

If this is the right equation then x would equal -0.5

(hope this helps)

Step-by-step explanation:

"The sum of 8 times a number (x) and 7 equals 3."

Let, "a number" = x

8x + 7 = 3

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

First, subtract 7 from both sides of the equation:

8x + 7 (-7) = 3 (-7)

8x = 3 - 7

8x = -4

Next, divide 8 from both sides of the equation:

(8x)/8 = (-4)/8

x = -4/8

x = -1/2

-1/2 is your number, or -0.5
