Factor the expression completely.

54 + 45x

9(6+5x)

Step-by-step explanation:

54 + 45x (Write out the original equation in standard form. This has already been done.)

=9(6) + 9(5x) (For this step, you rewrite 54 as 9(6) and 45 as 9(5).

=9(6+5x) (For this step, you factor out 9 because it is the greatest common denominator.)

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
