In the following equation, when x=0, what is the value of y?

3x + 4y = 12

(3)(0)+4y=12

Step 1: Simplify both sides of the equation.

(3)(0)+4y=12

0+4y=12

(4y)+(0)=12(Combine Like Terms)

4y=12

4y=12

Step 2: Divide both sides by 4.

4y

4

=

12

4

y=3

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
