What are the 2 possible answers for 5x plus 7y equals 1500?

Answer 1

This is a linear equation.

You can transform this into the form y = as follows:

5x + 7y = 1500

Subtract 5x from both sides:

5x (-5x) + 7y = 1500 (-5x)

7y = 5x - 1500

Then divide both sides by 7:

7y/7 = (5x - 1500)/7

y = (5/7)x - (1500/7)

In order to find the zeros for the equation, you can simply substitute 0 for one variable at a time, and then solve the equation for the other variable.

If we set y = 0,

0 = (5/7)x - (1500/7)

(1500/7) * (7/5) = x

x = 300

So (x = 300, y = 0) is one solution.

5x + 7y = 1500

Substituting 0 for x, we get:

7y = 1500

y = (1500/7) = approximately 214.29

The second solution is (x=0, y=214.29)
