$y = 13$
Answer for screen readers
$y = 13$
Steps to Solve
-
Write down the equation We start with the given equation: $$ y = mx - b $$
-
Substitute the given values Substitute $m = 3$, $x = 6$, and $b = 5$ into the equation: $$ y = (3)(6) - 5 $$
-
Perform the multiplication Multiply $3$ and $6$: $$ y = 18 - 5 $$
-
Perform the subtraction Subtract $5$ from $18$: $$ y = 13 $$
$y = 13$
More Information
The equation $y = mx - b$ is a linear equation.
Tips
A common mistake is to confuse the order of operations. Make sure to perform the multiplication before the subtraction. Also, ensure that you substitute the correct values for the corresponding variables.
