Question

substitute 3 X + 2 Y equal to 10 aand 12 x + 8 Y equal to 30​

Answer 1

Answer:

Step-by-step explanation:

3x+2y=10---(1)

12x+8y=30---(2)

--------------------------------

from (1)

3x=10-2y

x=10-2y/3

substitute in (2)

12(10-2y)/3+8y=30

4(10-2y)+8y=30

40-8y+8y=30

40=30

the equations have multiple solutionsi.e., infinite number of solutions
