a.3x+5x=4
b.3x+4=5x
c.3x=4+5x
d.3x-4=5x

Answer 1

its B cause 3times a number x increased by 4 is equal to five the number x.3x+4=5x

Answer 2

The value of x is 2 .

Option (b) is correct .

Explanation:

As given

Three times a number, x, increased by four is equal to five times the number, x.

Thus the equation becomes

3x + 4 = 5x

5x - 3x = 4

2x = 4

`x = (4)/(2)`

x = 2

Therefore the value of x is 2 .

Option (b) is correct .
