3x + 6y= 180What is x and y​

Mathematics
1 answer:
Diano4ka-milaya [45]3 years ago
3 0

Answer and explanation:

<h2>X</h2>

3x + 6y = 180  <em>Use the original expression to find x</em>

3x = 180 - 6y  <em>Subtract 6y by both sides</em>

\frac{3x}{3} = \frac{180}{3} - \frac{6y}{3}  <em>Divide by 3 to get x</em>

x = 60 - 3y

<h2>Y</h2>

x = 60 - 3y  <em>Use the new expression to find y</em>

x - 60 = - 3y  <em>Subtract 60 by both sides</em>

\frac{x - 60}{-3} = \frac{-3y}{-3}  <em>Divide by -3 to get y</em>

-\frac{x}{3} + 20 = y
