If 4x+5y=10 and x+3y = 8 then (5x+8y)/3=

aev [14]

First set up a system of equations and solve.

4x+y=10
x+3y=8
In order to have one variable cancel out, I will multiply the top by -3.

-12x-3y=-30
x+3y=8
____________
-11x=-22
x=2

Then plug the x value into one of the original equations.

(2)+3y=8
3y=6
y=2

Now plug both into the final equation:
5(2)+8(2)/3
(10+16)/3
26/3
8.667 is the answer or 26/3.

What is the Quadratic formula

REY [17]

The quadratic formula is one of the ways to find a solution to the quadratic equation, alongside graphing and completing the square. The quadratic formula can be represented as $x= \frac{-b \sqrt{ b^{2}-4ac } }{2a}$ where a is the squared value, b is the multiplied value, and c is the constant.
