Answer:

4.)

a. x=  <u>-6</u> y-3

               5

b. x= <u>5</u> y + <u>13</u>

         4        4

3.)

a. x= <u>-4y</u> + <u>-8</u>

         5       5

b. x=<u> 3</u> 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=  <u>-6</u> 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= <u>5</u> y + <u>13</u>

    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= <u>-4y</u> + <u>-8</u>

     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=<u> 3y</u>+3

    2
