Question

Решить уравнение:14-y=19-11y; 0,5a+11=4-3a;1,2n+1=1-n;1,7-0,3m=2+1,7m;0,8x+14=2-1,6x

Answer 1

14-y=19-11y
-y+11y=19-14
10y=5
y=2

0.5a+11=4-3a
0.5a+3a=4-11
3.5a=-7
a=-2

1.2n+1=1-n
1.2n+n=1-1
2.2n=0
n=0

1.7-0.3m=2+1.7m
-0.3m-1.7m=2-1.7
-2m=0.3
m=- 0.15

0.8x+14=2-1.6x
0.8x+1.6x=2-14
2.4x=-12
x=-5
