What is the solution of the system of equations? {4x−3y=152x+2y=4 enter your answer in the boxes.

3, -1

I just took the test so enjoy

x = 3, y = -1

Step-by-step explanation:

To solve this, we will eliminate x.  In order to do this, we must multiply the bottom equation by 2:

To eliminate x, we will subtract the bottom equation from the top one:

Divide both sides by -7:

-7y/-7 = 7/-7

y = -1

Substitute this into the first equation:

4x-3(-1) = 15

4x--3 = 15

4x+3 = 15

Subtract 3 from each side:

4x+3-3 = 15-3

4x = 12

Divide both sides by 4:

4x/4 = 12/4

x = 3

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

c. side angle side. u shares the same sides
