Answer:
x = -5
y = 4
Step-by-step explanation:
3x + 4y = 1 /*(-4)
4x + 5y = 0 /*3
---------------------
-12x - 16y = -4
12x + 15y = 0 +
---------------------
-y = -4
y = 4
---------------------
12x = -15y
12x = -60
x = -5

Answer:
Step-by-step explanation:
Brain correctly use a method of completing the square to solve the equation:
His First Step is to: Take the Constant Term to the Right Hand Side
The Next Step Would be to:
- Divide the Coefficient of x by 2
- Square It
- Add it to both Sides
In this case, the Coefficient of x = 7
- Divided by 2 =
- Squaring It, we have:
It is this number that is added to both sides in the manner below:
A Because if you do 156 x 20 it equals 3120. It’s A because the volume formula is Length x Width x height, And 156 and 20 were the only numbers given.
