For a <span>system of two linear equations to have more than one
solution, the lines representing the equations must coincide, i.e. must
be the same or a multiple of each other. In that case, the system will have infinitely many solutions.

-8x-8y=0 (divide both sides by -8, you get:) x+y=0, x=-y
-8x2y=-20 (divide both sides by -16:) xy=20/16=5/4
plug the first simplified equation into the second one,
-y²=5/4...This does not have a solution, are you sure you typed the second equation correctly?
You can get all the answeres easily.
Heres number 1: -1/5

The first step to solve the equation 1 1/2 + 2 1/3 = ? is (a) First, you should convert the mixed numbers to improper fractions.
<h3>How to determine the first step?</h3>
The equation is given as:
1 1/2 + 2 1/3 = ?
The terms in the equation are mixed numbers.
So, the first stem is to convert the mixed numbers to improper fractions
Hence, the true statement is (a) First, you should convert the mixed numbers to improper fractions.
