Look at the picture.

Therefore we have the equation:

10y - 29 = 7y + 19       <em>add 29 to both sides</em>

10y = 7y + 48          <em>subtract 7y from both sides</em>

3y = 48      <em>divide both sides by 3</em>

y = 16



3x + 7 = 5x - 21            <em>subtract 7 from both sides</em>

3x = 5x = -28         <em>subtract 5x from both sides</em>

-2x = -28     <em>divide both sides by (-2)</em>

x = 14

What is the equation of a line that passes through the point (5, −4) and is parallel to the line whose equation is 2x + 5y = 10?
Artyom0805 [142]
A quick way to solve this problem involves copying the given equation:

2x + 5y = 10

dropping the final 10, and
substituting the given x and y values:  (5, -4).  

Then:

2(5) + 5(-4) = C           C = 10-20 = -10

Thus, the equation of this new, parallel line is 2x + 5y = -10.
