Respuesta :
3y = x + 6
y – x = 3 -----------> x=y - 3 (substitute in 1st equation)
3y = y - 3 +6
3y - y = 3
2y = 3
y = 2/3
x= y - 3 = 2/3 -3 = 2/3 - 9/3 = - 7/3
x= - 7/3, y = 2/3
y – x = 3 -----------> x=y - 3 (substitute in 1st equation)
3y = y - 3 +6
3y - y = 3
2y = 3
y = 2/3
x= y - 3 = 2/3 -3 = 2/3 - 9/3 = - 7/3
x= - 7/3, y = 2/3
3y = x + 6
y = x + 3 Subtract:-
2y = 0 + 3
y = 3/2 = 1.5
Plug this value of y into the first equation:-
3(1.5) = x + 6
x = 4.5 - 6 = -1.5
Answer is x = -1.5, y = 1.5
y = x + 3 Subtract:-
2y = 0 + 3
y = 3/2 = 1.5
Plug this value of y into the first equation:-
3(1.5) = x + 6
x = 4.5 - 6 = -1.5
Answer is x = -1.5, y = 1.5
