Use linear combination. To solve system <br> -2x+7y=10<br> X-3y=-3
Tamiku [17]
-2x + 7y = 10 ⇒ -2x + 7y = 10
   x - 3y = -3   ⇒ <u>-2x + 6y = 6  </u>
                                      y = 4
                         -2x + 7(4) = 10
                           -2x + 28 = 10
                          <u>         -28   -28</u>
                                   <u>-2x</u> = <u>-18</u>
                                    -2      -2
                                       x = 9
                                  (x, y) = (9, 4)

PLEASE HELP! THANK YOU!<br><br> Explain your answer!!!
Brrunno [24]

Answer:

1) y = 1/2 x + 3 and y = 1/2 x  are parallel

2) y = 1/2 x + 4   and   y = 1/2 x + 1  are parallel

Step-by-step explanation:

Two lines are parallel only if their slope is equal.

1)

In the first problem:

y = 1/2 x + 3 and y = 1/2 x have same slope ( i.e slope = 1/2)

That means these two equations are parallel to each other.

2)

In the second problem:

y = 1/2 x + 4   and   y = 1/2 x + 1 have same slope( i.e slope = 1/2)

Hence above two equations are parallel to each other.
