Question

Solve for x using cross multiplication

Answer 1

x = 2

Explanation:

using the method of cross- multiplication

`(a)/(b)` =
`(c)/(d)` ⇒ ad = bc

given
`(x+4)/(3)` =
`(x+6)/(4)`, then

4(x + 4) = 3(x + 6) ← distribute parenthesis

4x + 16 = 3x + 18 ( subtract 3x from both sides )

x + 16 = 18 ( subtract 16 from both sides )

x = 2
