Question

С ОБЕСЕДОВАНИЯМ!!!! 3=4 (x+2)
-7=5 (х+5)
7 (х-1)=3х
5 (х-3)=44
4 (х+6)=х

Answer 1

1)
3 = 4(x + 2)
3 = 4x + 8
4x + 8 = 3
4x = -5
x = - $\frac{5}{4}$ = -1,25

2)
-7 = 5(x + 5)
-7 = 5x + 25
5x + 25 = -7
5x = -32
x = - $\frac{32}{5}$ = -6,4

3) 
7(x - 1) = 3x
7x - 7 = 3x
7x - 3x = 7
4x = 7
x = $\frac{7}{4}$

4)
5(x - 3) = 44
5x - 15 = 44
5x = 59
x = $\frac{59}{5}$ = 11,8

5)
4(x + 6) = x
4x + 24 = x
4x - x = -24
3x = -24
x = - $\frac{24}{3}$ = -8
