Answer:

no solution

Step-by-step explanation:

6x - 3y = 7 → (1)

- 2x + y = - 8 → (2)

multiplying (2) by 3 and adding to (1) eliminates the variables

- 6x + 3y = - 24 → (3)

add (1) and (3) term by term

0 + 0 = - 17

0 = - 17 ← false statement

This indicates the system has no solution

Complete the solution of the equation find the value of y when x equals 2. -8x - 5y = -1
tatuchka [14]

Answer: y = -3

<u>Step-by-step explanation:</u>

-8x - 5y = -1

<u>+8x        </u>  <u>+8x </u>

       -5y = 8x  - 1

       <u> ÷-5 </u> <u> ÷-5</u>  <u>÷-5</u>

           y = -\frac{8}{5}x + \frac{1}{5}

       y(2) = -\frac{8}{5}(2) + \frac{1}{5}

               = -\frac{16}{5} + \frac{1}{5}

               = -\frac{15}{5}

                = -3
