Answer:
x =23/11, y =4/11
Step-by-step explanation:
subtract equation 1 from equation 2
2x-x + 5y-(-3) =6-1
x + 8y = 5
make x the subject of formula
x = 5-8y(equation#)
substitute x = 5-8y in equation 1
5-8y-3y = 1
5-11y = 1
collect like terms
5-1 = 11y
4= 11y
divide both sides by 11
4/11 = 11y/11
y = 4/11
put y = 4/11 in equation #
x = 5-8(4/11)
x = 5-32/11
LCM= 11
x = 55-32/11
x = 23/11
so, x =23/11, y = 4/11
