4 (x-0.123) + 7 (y + 3.45) = 1 5 (x-0.123) - (y + 3.45) = 11 solving binary linear equations by substitution method

4 (x-0.123) + 7 (y + 3.45) = 1 5 (x-0.123) - (y + 3.45) = 11 solving binary linear equations by substitution method

{4(X-0.123)+7(Y+3.45)=1{5(x-0.123)-(y+3.45)=11
4(X-0.123)+7(Y+3.45)=1
5(x-0.123)-(y+3.45)=11
Solution
x=2.123
y=-4.45
