Laila has to pay $75 regardless of how many shirts she gets but has to pay an additional $8 per shirt. So when you set up your equation you are going to set it equal to c (the total cost). So c=75+8x. The reason there is a variable after 8 is because we aren’t sure how many shirts she’s buying yet.
Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
