rozwiąż równania : -8z+5= -2-1 -2m+7=m-6 6-5x=2-7 5t+1=8-6t prosze o pomoc bo mi coś nie wychodzi ;)

-8z+5= -2-1 -8z=-2-1-5 -8z=-8 z=1 -2m+7=m-6 -2m-m=-6-7 -3m=-13 m=4 1/13 6-5x=2-7 -5x=2-7-6 -5x=-11 x=2,2 5t+1=8-6t 5t+6t=8-1 11t=7 t= 1 4/7

-8z+5=-2-1 -8z=-2-1-5 -8z=-8 /: (-8) z=1 -2m+7=m-6 -2m-m=-6-7 -3m=-13 /: (-3) m=13/3 m= 4 i jedna trzecia 6-5x=2-7 -5x=2-7-6 -5x=-11 /: (-5) x= 11/5 x= 2 i jedna piąta 5t+1=8-6t 5t+6t=8-1 11t=7 /: 11 t=7/11

-8z+5= -2-1 -8z = -2-1-5 -8z = -8 /:(-8) z = 1 -2m+7=m-6 -2m = m-6 -7 -2m -m = -13 -3m = -13/:(-3) m = 13/3 m =4 i 1/3 6-5x=2-7 -5x = 2-7-6 -5x = -11/: (-5) x = 11/5 x = 2 i 1/5 5t+1=8-6t 5t + 6t = 8 - 1 11t = 7 / : 11 t = 7/11
