Question

solve for x and verify your result: (a) 3x+4( x-2)=3(x-4)+2. (b). x-(4-x)=3(x-4)-4. (c) 3(2x+1)-4(x-2)=0​

Answer 1

Step-by-step explanation:

a)

3x+4x-8=3x-12+2

7x-8=3x-10

7x-3x=-10+8

4x=-2

x=-1/2

b)

x-(4-x)=3(x-4)-4

x-4-x=3x-12-4

-4=3x-16

3x=12

x=4

c)

3(2x+1)-4(x-2)=0

6x+3-4x+8=0

2x+11=0

2x=-11

x=-11/2

Answer 2

a) 3x+4(x-2) =3(x-4) +2

=3x+4x-8=3x-12+2

=7x-3x=8-10

4x= -2

= x = -2/4

= -1/2
