Question

Plz help me asnwer this

Answer 1

Answer:

x= 0

y= -3

Step-by-step explanation:

6x-5y=15

substitution...

6(y+3)-5y=15

6y+18-5y=15

y+18=15

-18     -18

y= -3

substitution again...

6x-5(-3)=15

6x+15=15

-15      -15

6x=0

/6   /6

x= 0

Answer 2

Answer:

(0, -3)

x = 0

y = -3

Algebra I

• Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

6x - 5y = 15

x = y + 3

Step 2: Solve for y

Substitution

1. Substitute in x:                               6(y + 3) - 5y = 15
2. Distribute 6:                                   6y + 18 - 5y = 15
3. Combine like terms:                      y + 18 = 15
4. Isolate y:                                         y = -3

Step 3: Solve for x

1. Define original equation:                    x = y + 3
2. Substitute in y:                                     x = -3 + 3
3. Add:                                                      x = 0
