Substitute y
6x + 5(2x – 14) = -6
use distributive property
6x + 10x – 70 = -6
add terms together
16x = 64
isolate x
16x/16 = 64/16
x = 4
to find value of y, use your x value in the second equation
y = 2(4) – 14
y = -6
Verify you are correct
6(4) + 5(-6) = -6
Two consecutive integers would be 13 and 14
because 13 x 13 = 169 and 14 x 14 = 196 and the inequality fits inbetween perfectly.

The first thing we should do is see what relationship we have:
Table is feet to yards 3-1
a. Describe the relationship between the number of feet and the number of yards
That is to say:
1Yarda = 3 feet
b. Write an expression for the number of yards in f feet
Let
y = Yard
f = feet
We have the following expression for the conversion:
y = (1/3) f
c. Find the number of yards in 63 feet
For this case we must substitute in the expression found the value of f = 63.
y = (1/3) f
y = (1/3) (63)
y = 21
answer:
1Yarda = 3 feet
y = (1/3) f
y = 21
