Question

4. Solve each of the following equations.
(1) 8x -4 = 2x+8
(ii) 36 - 6x = 11
(iii) 5x+1=7
(iv) 3x-1/4=1/4x+2
(v)6/7x-1/7=11
(vi) y+9 = 15+ 3y​

Answer 1

Step-by-step explanation:

1)Given equation is 8x -4 = 2x+8

=>8x-2x=8+4

=>6x=12

=>x=12/6

=>x=2

Solution( X)=2

2)Given equation is 36 - 6x = 11

=>36-11=6x

=>25=6x

=>x=25/6

Solution (X)=25/6

3)Given number is 5x+1=7

=>5x=7-1

=>5x=6

=>x=6/5

Solution (X)=6/5

4)Given number is 3x-1/4=1/4x+2

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

=>(12x-3x)/4=(8+1)/4

=>9x/4=9/4

=>X=9/4×4/9

=>X=1

Solution (X)=1

5)Given equation is 6/7x-1/7=11

=>6/7x=11+1/7

=>6/7x=(77+1)/7

=>6/7x=78/7

=>6x=78

=>x=78/6

=>x=13

Solution (X)=13

6)Given equation is y+9 = 15+ 3y

=>15+3y=y+9

=>3y-y=9-15

=>2y=-6

=>y=-6/2

=>y=-3

Solution (y)=-3
