Question

Solve the following equation for x: 5x + 3y = 15.
x = y − 3
x = y + 3
x = y + 3
x = y − 3

Answer 1

Answer:

x = 3 - (3 y)/5

Step-by-step explanation:

Solve for x:

5 x + 3 y = 15

Subtract 3 y from both sides:

5 x = 15 - 3 y

Divide both sides by 5:

Answer:  x = 3 - (3 y)/5

Answer 2

Solved the equation for x to get $x = 3-\frac{ 3y}{5}$.

How to solve the equation?

The equation can be solved by equating all the terms other than the x term to one side. Now simply the whole equation by dividing the equation by the coefficient of the x term.

The equation can be solved as shown below:

The given equation is:

5x + 3y = 15

The equation can be evaluated as shown below:

5x + 3y = 15

Move the y term to the right side:

5x = 15 - 3y

Now divide the entire equation by 5:

$x =\frac{15-3y}{5}$

$x = 3-\frac{ 3y}{5}$

The value of x is found. We have found the value of x to be $x = 3-\frac{ 3y}{5}$.

Therefore, we have solved the equation for x to get $x = 3-\frac{ 3y}{5}$.
