Question

x -5=8 x+4=3 x+39= -79 x -11=28 x+109=5 4x -1=3x-3 3x-6=2x-4 7x-28=2x-4 10x-20=7x+4 4x-15= -2x+3

Answer 1

x - 5 = 8
x = 9 + 5
x = 14 


x + 4 = 3
x = 3 - 4
x = -1


x + 39 = -79
x = -79 -39
x = -118


x - 11 = 28
x = 28 + 11
x = 39 


x + 109 = 5
x = 5 - 109
x = -104


4x - 1 = 3x - 3
4x - 3x = -3 + 1
x = -2 


3x - 6 = 2x - 4
3x - 2x = -4 + 6
x = 2 


7x - 28 = 2x - 4
7x - 2x = -4 + 28
5x = 24
x = $\frac{24}{5}$


10x - 20 = 7x + 4
10x - 7x = 4 + 20
3x = 24
x = $\frac{24}{3}$
x = 8


4x - 15 = -2x + 3
4x + 2x = 3 + 15
6x = 18
x = $\frac{18}{6}$
x = 3
