Substitute what you know y is equal to into the equation:
y = x + 2
3/2x - 2 = x + 2
Then you can simplify your equation by multiplying both sides by 2 to eliminate the fraction which will give you:
3x - 4 = 2x + 4
Add the -4 to the other side to get 8 and subtract the 2x from the 3x so you have:
x = 8 Now solve for y by substituting your value for x into the other equation:
y = 3/2(8) - 2 Simplify by combining your numbers and you get:
y = 10 Check your answer by substituting y and x into the original equation:
(10) = (8) - 2
Correctly done! So your answers are x = 8 and y = 10
8 7/8+(7 5/6) - 2 1/3)
71/8 +(47/6 - 7/3)
71/8+ 11/2
115/8
(3x^2- 5)(x^2+2) that is the answer
For the first inequality, subtract 5 from both sides to get

For the second inequality, subtract 1 from both sides to get

Divide both sides by 6:

So, x has to be greater than or equal to -2, or less than -5, which is option D
The answer to that is -7.65. When looking at the problem I estimated around -8
