X+4=3x+9 how to solve this?

Mathematics

Basile [38]3 years ago

Answer:

x = - \frac{5}{2}

Step-by-step explanation:

x + 4 = 3x + 9 ( subtract x from both sides )

4 = 2x + 9 ( subtract 9 from both sides )

- 5 = 2x ( divide both sides by 2 )

- \frac{5}{2} = x

Subtract 3x from both sides which would be -2x+4=9 then subtract 4 from each side which would be -2x =5 then divide by -2 which would be x=2.5 or 2 1/2
