Ответ:
(x,y) = (0.5, 1.5) = (1/2, 3/2)
Step-by-step explanation:
these are tricky you have to manipulate the equations to get the x and y by itself and then solve for that
3x+y=3
x+y=2 (multiply this equation by 3) =
3x+3y=6
now subtract the equations
(3x+3y=6) - (3x+y=3) = 2y=3 so y = 3/2 or 1.5
now plug in the y value for one of the equations and solve for x
x + 3/2 = 2
x = 1/2 or 0.5
