Question

is $y = 1$ a solution to this equation?
$7 = 7y$
yes no

Explanation:

Step1: Substitute y = 1 into the equation

Substitute \( y = 1 \) into the right - hand side of the equation \( 7 = 7y \). The right - hand side becomes \( 7\times1 \).
\[7\times1 = 7\]

Step2: Compare both sides

The left - hand side of the equation is 7, and after substitution, the right - hand side is also 7. Since the left - hand side is equal to the right - hand side when \( y = 1 \), \( y = 1 \) satisfies the equation.

Answer:

yes
