Question

Решите уравнения:
100+11x = -8x+5
5 (2z-6) = 6z - 14
4+3t = 8t - t
4 (10-5y) - 4 = 0

Answer 1

100+11x = -8x+5 
11x+8x=5-100
19x=-95
x=-95:19
x= -5

5 (2z-6) = 6z - 14
10z-30=6z-14
10z-6z=30-14
4z=16
z=16:4
z=4

4+3t = 8t - t 
4+3t=7t
7t-3t=4
4t=4
t=1

4 (10-5y) - 4 = 0
40-20y-4=0
36-20y=0
20y=36
y=36:20
y=1,8
