Question

2. 2x + y = 7; 4x - 3y + 1 = 0. solve for x and y​

Answer 1

Answer:

x=2, y=3

Step-by-step explanation:

2x+y=7-----(1) and 4x-3y+1=0

⇒4x-3y=-1---(2)

Adding (1) and (2),

  2x+y=7

+ 4x-3y=-1

⇒6x-2y=6

⇒2(3x-y)=6

⇒3x-y=3-----(3)

Adding (1) and (3),

  2x+y=7

+3x-y=3

⇒5x=10

⇒x=10/5

⇒x=2

Substituting 'x' in (1),

2(2)+y=7

⇒4+y=7

⇒y=7-4

⇒y=3
