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

x = (-3y)/5 + 3

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 3y from both sides:

5x + 3y (-3y) = 15 (-3y)

5x = -3y + 15

Next, divide 5 from both sides of the equation:

(5x)/5 = (-3y + 15)/5

x = (-3y + 15)/5

x = (-3y)/5 + (15)/5

x = (-3y)/5 + 3

x = (-3y)/5 + 3
