Solve each system by elimination.
4) 5x +6y =-15 4x - 5y=13

3) (5x+4y=-8) 2x - 3y = 6

please show work cause I'm lost.

4.)

a. x=  -6 y-3

               5

b. x= 5 y + 13

         4        4

3.)

a. x= -4y + -8

         5       5

b. x= 3 y+3

         2

Step-by-step explanation:

4.)  

a. 5x+6y=-15

Add -6y to both sides.

5x+6y+−6y=−15+−6y

5x=−6y−15

Divide both sides by 5.

5x ÷ 5= -6y-15 ÷5      

x=  -6 y-3

      5

b. 4x - 5y=13

Add 5y to both sides

4x−5y+5y=13+5y

4x=5y+13

Divide both sides by 4

4x÷4= 5y+13÷4

x= 5 y + 13

    4        4

5.)

a.  (5x+4y=-8)

Add -4y to both sides

5x+4y+−4y=−8+−4y

5x=−4y−8

Divide both sides by 5

5x÷5= -4y-8÷5

x= -4y + -8

     5       5

b. 2x - 3y = 6

Add 3y to both sides.

2x−3y+3y=6+3y

2x=3y+6

Divide both sides by 2.

2x÷2= 3y+6÷2

x= 3y+3

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
