Can someone help me solve these systems using elimination?

8x-6y=-20

-16x+17y=30

Please show your steps so I can learn too. Thank you

Step-by-step explanation:

8x-6y=-20

y = mx + b in which is the slope intercept of the line where m is the slope and b is the y intercept.

converting to y = 4 x + 10

3. 3

for the line in the form of y = mx + b, the slope is m and y intercept is b.

I think so and I hopefully it works..

$7.

Step-by-step explanation:

It is given that the printing company charges a certain amount for each shirt plus a setup fee of $40.

Let x be the cost of each t-shirt.

There are 21 students in the drama club. So, total cost of 21 t-shirts is

It is given that the t-shirt order costs a total of $187.

Divide both sides by 21.

Therefore, the cost of each t-shirt is $7.
