The equation 5x-10y=30is written in standard form. what is the first step when solving for x? add 5x to both sides of the equation. subtract 5x from both sides of the equation. add 10y to both sides of the equation. subtract 10y from both sides of the equation.

Write two subtraction equations that are equivalent to 5 + 12 = 17.
