Question

2. Solve the following pairs of linear equations
by the method of substitution :
(1) 2x + 3y = 4, 3x - 4y = 23
(2) 5x + 2y = 23, 3x - 5y = -11
(3) 4x + 5y = 19, 2x - 7y = 19
(4) 5x - 3y = 0, 3x - 5y = 16​

Answer 1

Step-by-step explanation:

1) y= -2,x=5

2)x=3,y=4

3)x= 6,y= -1

4)x=24, y= 5
