Question

X + 4y = 13

What is the value of x?

Answer 1

Hi! The correct answer is x=13-4y!

Explanation:

~Subtract 4y from both sides of the equation~

Answer 2

13-4y

Explanation:

Without a second equation it is impossible to give a numerical value for x, but x can be expressed in terms of y.

This equation is called a "literal equation" since there are more than one variable, but only one equation (it is not a system of equations).

Therefore, solve for x by subtracting 4y from both sides:

x+4y=13

-4y -4y

x=13-4y
