Answer:
x = 5/3
y = -8/3
Step-by-step explanation:
To solve y = 2x - 6 substitute the y for -x - 1 and solve for x.
-x - 1 = 2x - 6 Now you can solve this like a regular inequality. Start by subtracting 2x on both sides.
-3x - 1 = -6 Now add 1 to both sides
-3x = -5 Divide by -3 on both sides
x = 5/3 (the negatives cancel and become positive)
Because you have x, you can go back and properly solve for y. Substitute x for 5/3
y = 2(5/3) - 6 Simplify the right side to get your answer.
y = 10/3 - 6 In order to subtract 6, you first have to convert it to a fraction with a denominator of 3. To do this, put 6 over 1 (6/1) then find the least common denominator of 3 and 1, which is 3. Now multiply 1 by 3 and 6 by 3 to get 18/3
y = 10/3 - 18/3
y = -8/3

Answer:
1/4, 1/2, .67, 3/4, 7/8, 1.78, 3.2, 6, 9
868 is about 870, and 28 is about 30, so your expression would be 870 divided by 30 which would be 29 and the actual answer is 31, so your estimate would be close to your actual answer.
