Question

3. Solve the following pair of linear equations by the
substitution and cross-multiplication methods:
8x + 5y = 9; 3.x + 2y = 4​

Answer 1

Answer:

Step-by-step explanation:

8x+5y=9

3x+2y=4

So 8x+3x+5y+2y=9+4

11x+7Y=13

Answer 2

Answer:

8x+5y=9, 3x+2y=4

8•x+5•y=9

3•x+2•y=4

8x+5y = 9

3x+2y = 4

x = -2

y = 5
