Question

Solve the equation and check your answer:

7 − x /

5x + 1

= 3
​

Answer 1

x = 1/4

explain

7-x/5x+1 = 3

7-x = 3(5x+1)

7-x =15x+3

-15x-x = -7+3

-16x = -4

x = 4/16

x = 1/4

Answer 2

Answer: -4/19

Step-by-step explanation:

7-x/5x+1 = 3

lcm of 5x+1,1 is 5x+1

7(5x+1) / 5x+1-x/5x+1=3

35x+7/5x+1- x/5x+1=3

35x+7-x / 5x+1=3

34x+7 / 5x+ 1=3

34x+7=3(5x+1)

34x+7=15x+3

34x-15x=3-7

19x=-4

x=-4/19
