Question

2x+y = 5 and x+3y=10 solve linear equation with 2 variable

Answer 1

Answer:

x=b1c2-b2c1/a1b2-a2b1, y=c1a2-c2a1/a1b2-a2b1

Step-by-step explanation:

2x+y=5 and x+3y=10,

x={1}{10} - {3}{5}/{2}{3} - {1}{1}

x=10-15/6-1

x=-5/5

x=-1

y={5}{1} - {10}{2}/{2}{3} - {1}{1}

y=5-20/6-1

y=-15/5

y=-3

2{-1}+{-3}=5

=-2-3=5

=5=5

={-1}+3{-3}=10

=-1-9=10

=10=10.
