Question

what is the solution to the equation? 56 = -0.7y; y = 39.2; y = -39.2; y = -8; y = -80

Explanation:

Step1: Isolate y by dividing both sides by -0.7

To solve for \( y \) in the equation \( 56 = -0.7y \), we divide both sides of the equation by \( -0.7 \). This gives us the formula:
\[
y = \frac{56}{-0.7}
\]

Step2: Calculate the value of y

Now we perform the division. \( 56 \div (-0.7) \) is the same as \( - (56 \div 0.7) \). Since \( 56 \div 0.7 = 80 \), we have:
\[
y = -80
\]

Answer:

\( y = -80 \) (corresponding to the option \( y = -80 \))
