Answer: y = -22
Step-by-step explanation: To find the value of y when x is equal to -3, we simply substitute a -3 in for x in the given equation.
So we have y = 5(-3) - 7.
Notice that I used parentheses when I substituted the -3
into the equation. That's a really good habit to get in.
Now, 5(-3) is -15.
So we have -15 (-7) which is -22.
This means that y = -22.
