Solve y-2x=1, 3x-4y=1 using substitution m

y-2x=1

3x-4y=1

y=1+2x

3x-4y=1

y=1+2x

3x-4(1+2x)=1

y=1+2x

3x-4-8x=1

y=1+2x

-5x-4=1

y=1+2x

-5x=1+4

y=1+2x

-5x=5

y=1+2x

x=-1

y=1+2*(-1)

x=-1

y=1+(-2)

x=-1

y=-1

x=-1

i dont know if you cant find a way its best to actually add all of them start from 105 tho
