4-16x plus 28y equals?
4(1-4x+7y)
How do you solve 3.5y2 plus 2.6y-8.2 equals 4y2-6.9y using the quadratic formula?
Multiply each item by 10 to give whole numbers then move items to give ay2+by+c=0 3.5y2+2.6y-8.2=4y2-6.9y multiply by 10 35y2 + 26y - 82 = 40y2 -69y subtract 35y2 from both sides 26y - 82=5y2 -69y subtract 26y from both sides -82 = 5y2 - 95y add 82 to each side 0 = 5y2 - 95y +82 or 5y2 - 95y +82 = 0
What is the recoprocal of 5y2 plus 9y?
1/5y2+9
How do you find the difference 28y-16y?
28y - 16y = 12y.
What is 15y2 plus 45y - 9 equals 4y - 5y2?
15y2 + 45y - 9 = 4y - 5y2; thus, 20y2 + 41y - 9 = (5y - 1)(4y + 9) = 0. Therefore, the solution to the equation given is, y = 1/5 or -2¼.
How do you solve monimals?

What is 15y2 plus 45y - 9 equals 4y - 5y2?
15y2 + 45y - 9 = 4y - 5y2; thus, 20y2 + 41y - 9 = (5y - 1)(4y + 9) = 0. Therefore, the solution to the equation given is, y = 1/5 or -2¼.
4x-5y2 12x8 plus 15y solve by elimination?
Without any equality signs the given terms can't be considered as simultaneous equations and so therefore no solutions are possible.
