Question

x_2y=0 and 3x+4y_20=0 slove this equation by graphicall method

Answer 1

\begin{lgathered}x - 2y = 0 then \\ x = 2y \\ and \\ 3x + 4y =20 \\ 3 \times 2y +4y = 20 \\ 6y + 4y = 20 \\ 10y = 20 \\ y = 2 \\ so \\ x = 2y \\ = 2 \times 2 = 4\end{lgathered}

x−2y=0then

x=2y

and

3x+4y=20

3×2y+4y=20

6y+4y=20

10y=20

y=2

so

x=2y

=2×2=4
