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

x = -

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 )

- = x

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
