Question

Need step by step explanation ​

Answer 1

Answer:

1. 3x - 1/4 =8

3x = 8 +1/4

3x=(32+1)/4

3x=33/4

3x=8.25

X=8.25/3

X=2.75=3

2. 2/3x+1=5

2/3x=5-1

2/3x=4

2x=4×3

2x=12

X=12/2

X=6.

Or

X+1=5-2/3

X+1=(15-2)/3

X+1=13/3

X+1=4.3

X=4.3-1

X=3.3.

Answer 2

Step-by-step explanation:

1) 3x - 1/4 =8

lcm = 4

12x - 1 = 8

4

12x -1 = 8×4

12x - 1 = 32

12x = 32+1

12x = 33

x = 33/12

2)2/3x + 1 = 5

lcm =3

2x + 3 = 5

3

2x + 3 = 5×3

2x+ 3 = 15

2x = 15 -3

2x = 12

x =6
