Rozwiąż równania, podaj całe obliczenia. Prosze szybko , bo mam to na jutro!
7x+2 = 5+3x+9
-5x+12+x =2x-12
x-3+3*4-x =5
3(x-4)-2(2x-5)= -4
2(x+4/)-5(x3)= 2
(3-2x)-(x+4)-(2x+5)= (3x-4)-(5x+7)
6(x+1)+3(2-x)= -2(4-x)+9(x+8)
3(3-x)+2x= 8-2(x-1)
x-(7+2x)= 2(x-1)+1
2x-7-[ 3-2x-2(1-2x)]= x-11
x/3 - 5/6 = 1/12 - x/2
7/9 + x/2 = 3/2 - x/18
x/9 + 1/2 = 5/4 - x/ + 1/2
