What is the value of x in the equation 7x + 2 y = 48, when y = 3?

COF

x = 6

x = 7

x = 8

x = 9

The answer is 6 bc i calculated it

x=6

Step-by-step explanation:

We are given the equation

7x+2y=48

We are also given y=3. Since we know y is equal to 3, we can substitute 3 in for y.

7x+2 (3) = 48

Multiply 2 and 3

7x+6=48

Now, we need to solve for x. To do this, we have to get x by itself. First, subtract 6 from both sides, since 6 is being added on.

7x+6-6=48-6

7x=42

Next, divide both sides by 7, because 7 and x are being multiplied. This will cancel out the 7, and leave x by itself.

7x/7=42/7

x=6
