Answer:

Step-by-step explanation:

This triangle has 2 equal sides. It also has 2 equal angles. They are marked

6x - 1
77

So the equation is 6x - 1 = 77 Add 1 to both sides

6x i- 1 + 1 = 77 + 1

6x = 78 Divide by 6

6x/6 = 78/6

x = 13

Ierofanga [76]

Answer:

option A

-2x + 4y = 4

-3x + 6y = 6

Step-by-step explanation:

In option A, if the student multiply the first equation by 3 and the second equation by -2, then the equations become

-6x+12y = 12 and

6x-12y =-12

If she adds both equations, she will get 0 = 0

This means that the system has infinite number of solutions.

Hence, the student could have started with equations -2x + 4y = 4 and -3x + 6y = 6.
