You can use elimination by adding the two equations to "cancel out" one of the variables. in this example y will cancel out.

2x + y = 3
+
2x - y = 4
________
2x = 6
x = 3

now that we know our x value, we can plug it into one of the other equations to get our y value.

2(3) + y = 3
6 + y = 3
y = -3

your answer for this system is x=3, y=-3

What is the fully factored form of the expression 45x²y2 + 18x3

Llana [10]

Answer:

9x^2(5y^2 + 2x).

Step-by-step explanation:

First find the Greatest Common Factor of the 2 terms.

GCF of 18 and 45 = 9

GCF of x^2 and x^3 = x^2.

The complete GCF is therefore 9x^2.

So, dividing each term by the GCF, we obtain:

9x^2(5y^2 + 2x).
