a)
[tex] \frac{1}{2} x - 4 = x - 6[/tex]
b)
[tex]4(x - 1) = 6(1 + x)[/tex]
​

Answer 1

a)

[tex]\frac{1}{2}x - 4 = x - 6[/tex]          /*2

x - 8 = 2x - 12

x - 2x = -12 + 8

-x = -4

x = 4

b)

4(x-1) = 6(1+x)

4x - 4 = 6 + 6x

4x - 6c = 6 + 4

-2x = 10            /:(-2)

x = -5

Answer 2

Verified answer

[tex]a)\\\\\frac{1}{2} x-4=x-6\\\\\frac{1}{2} x-x=-6+4\\\\-\frac{1}{2} x=-2 /*(-2)\\\\x=4[/tex]

[tex]b) \\\\4(x-1)=6(1+x)\\\\4x-4=6+6x\\\\4x - 6x = 6 + 4\\\\-2x = 10/:(-2)\\\\x = -5[/tex]
