Question

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

x = negative three fifthsy − 3
x = negative three fifthsy + 3
x = three fifthsy + 3
x = three fifthsy − 3

Answer 1

x = negative three fifthsy + 3

Explanation:

5x + 3y = 15

Subtract 3y from both the sides,

5x = 15 - 3y

Divide by 5 on both sides,

x = -3y/5 + 15/5

x = -3y/5 + 3
