2 7/10 + 5/8 what is the answer

Well you first must get the fractions to have the same denominator. So you multiply 5/8 by 10 ( both top and bottom ) to get 50/80, and you multiply 7/10 by 8 to get 56/80. You ignore the whole 2 for now for it is not a fraction, and you add 56 plus 50 to get 106 and put it back over 80. 106/80, now since 106/80 is over 1 you can take 106 - 80 and get 26. 1 and 26/80 is what the two fractions add up to. Add the whole two to 1 and get 3 and 26/80 which can be simplified to 3 and 13/40.

Y=-x+2 <br> y=-5x-6 <br> What is y and x

tatyana61 [14]

To solve this system of equations, since y is already isolated in both equations, you can set the expressions to equal each other to solve for x:

-x + 2 = - 5x - 6
-x + 5x = -6 - 2
4x = -8
x = -2

Now that we have x, we can substitute it into one of the equations to find y:

y = -(-2) + 2
y = 2 + 2
y = 4

The last step is to substitute both values into both equations to see if they are correct:

4 = -(-2) + 2 --> 4 = 2 + 2 <--True
4 = -5(-2) - 6 --> 4 = 10 - 6 <--True

Answer:
x = -2
y = 4
