Question

1. 5x + 3 = 7x – 1. Find x

a. 1/3
b. ½
c. 1
d. 2

​

Answer 1

Answer :-

5x + 3 = 7x - 1

=> 5x - 7x = -3 - 1

=> -2x = -4

=> x = -4/-2

=> x = 2

Answer 2

Answer:

5x + 3 = 7x - 1

now collect like terms

3 + 1 = 7x - 5x

every time you move something it changes signs

4 = 2x anything multiplied is divided on the other side and vice versa

4/2 = x

2 = x
