Answer 1

Answer:

Answer:First eq:-

2x + 3y = 42x+3y=4

2x + 3y = 42x+3y=42x = 4 - 3y2x=4−3y

2x + 3y = 42x+3y=42x = 4 - 3y2x=4−3yx = \frac{4 - 3y}{2}x=24−3y

2x + 3y = 42x+3y=42x = 4 - 3y2x=4−3yx = \frac{4 - 3y}{2}x=24−3ywhen y=o

2x + 3y = 42x+3y=42x = 4 - 3y2x=4−3yx = \frac{4 - 3y}{2}x=24−3ywhen y=ox = \frac{4 - 3 \times 2}{2} = - 1x=24−3×2=−1

2x + 3y = 42x+3y=42x = 4 - 3y2x=4−3yx = \frac{4 - 3y}{2}x=24−3ywhen y=ox = \frac{4 - 3 \times 2}{2} = - 1x=24−3×2=−1when y=2

2x + 3y = 42x+3y=42x = 4 - 3y2x=4−3yx = \frac{4 - 3y}{2}x=24−3ywhen y=ox = \frac{4 - 3 \times 2}{2} = - 1x=24−3×2=−1when y=2x = \frac{4 - 3 \times 2}{2} = - 1x=24−3×2=−1

2x + 3y = 42x+3y=42x = 4 - 3y2x=4−3yx = \frac{4 - 3y}{2}x=24−3ywhen y=ox = \frac{4 - 3 \times 2}{2} = - 1x=24−3×2=−1when y=2x = \frac{4 - 3 \times 2}{2} = - 1x=24−3×2=−1Second eq:-
