Mógłby mi ktoś rozwiązać to równanie metodą podstawiana ? proszę :)
x-2y=3
4x+3y=2
x=3+2y
4(3+2y)+3y=2
12+8y+3y=2
11y=-10
y=-10/11
x=3+2*(-10/11)
x=3 - 20/11
x=3- 1 9/11
x=2 11/11 - 1 9/11
x=1 2/11
x = 3 + 2y
4( 3 + 2y) + 3y = 2
12+ 8y + 3y = 2
8y+3y = 2 -12
11 y = - 10
y = -10/11
x + 20/11=3
x = 3 - 20/11
x = 33/11 - 20/11
x= 13/11
x= 1 i 2/11
