The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base.
To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.
_______________
___ ____
(rounded)
Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.
So, your final answer would be (3.29, 4.87).
