Question

3x+y=2;
2x-2y=5
ka graph ​

Answer 1

given★

• 3x+y=2-------(1)

• 2x-2y=5------(2)

solution★

EQ (1) graph solve EQ

• $\implies3x + y = 2$

$\implies \star \pink{y = 2 - 3x }$

• when we put x=0

• $\implies \: y = 2 - 3(0) \\ \\ \\ \implies \: y = 2 - 0 \\ \\ \\ \implies \: y = 2$

• cordinate find (x,y)=(0,2)

• when we put x=1

• $\implies \: y = 2 - 3(1) \\ \\ \\ \implies \: y = 2 - 3 \\ \\ \\ \implies \: y = - 1$
• cordinate find (x,y)=(1,-1)

=====================================

EQ (2) graph solve EQ

• 2x-2y=5

$\implies2x = 5 + 2y \\ \\ \\ \implies \star\pink{x = \frac{5 + 2y}{2} }$

• when we put y=-1

• $\implies \: x = \frac{5 + 2( - 1)}{2} \\ \\ \\ \implies \: x = \frac{5 - 2}{2} \\ \\ \\ \implies \ \ x = \frac{3}{2} \\ \\ \\ \implies \: x = 1.5$
• cordinate find (x,y)=(1.5,-1)

• when we put y=-2

• $\implies \: x = \frac{5 + 2( - 2)}{2} \\ \\ \\ \implies \: x = \frac{5 - 4}{2} \\ \\ \\ \implies x = \frac{1}{2} \\ \\ \\ \implies \: x = 0.5$
• cordinate find (x,y)=(0.5,-2)
