Answer:
x= -2
y= -2
Step-by-step explanation:
y = 8x + 14
y = x
Now by subtraction of these two equation,
So 0 = 7x + 14
x = -2
y = -2
2 x 18 = 36
5 x 18 = 90
36 + 90 = 126
the coach should order 126 rolls of tape
Answer:
x =7
Step-by-step explanation:
2(x-3)+4=12 Remove the brackets on the left
2x - 6 + 4 = 12 Combine
2x - 2 = 12 Add 2 to both sides
2x - 2 + 2 = 12 + 2 Combine
2x = 14 Divide by 2
2x/2 = 14/2
x = 7
