Question

Solve the equation 3x + 4y = 16 for x O A. x=484 B. X = 3(16 - 47) C. x = 16 - 4y OD D. X= 4y 16 3 3

Answer 1

Solving for x, we have;

`x=(16)/(3)-(4y)/(3)`

Step-by-step explanation:

Given the equation;

`3x+4y=16`

We want to make x the subject of formula.

subtract 4y from both sides;

`\begin{gathered} 3x+4y-4y=16-4y \\ 3x=16-4y \end{gathered}`

divide both sides by 3;

`\begin{gathered} (3x)/(3)=(16-4y)/(3) \\ x=(16)/(3)-(4y)/(3) \end{gathered}`

Therefore, solving for x we have;

`x=(16)/(3)-(4y)/(3)`
