Question

3x +2y = 8

4x + y = 9 by substitution​

Answer 1

Answer:

x=2,y=1

Step-by-step explanation:

3(2)+2(1)=8

4(2)+1=9

Answer 2

4x+y=9

y=9-4x-----------i equation

3x+2y=8

3x+2(9-4x)=8-----------put i equation

3x+18-8x=8

-5x=-10

x=2------------------------ ii equation

y=9-4x--------------------put ii equation

y=9-4(2)

y=9-8

y=1

value of x=2 and y=1
