Answer:

  (x, y) = (-3 5/8, 1 5/16)

Step-by-step explanation:

Add y+14 to the second equation to get ...

  3.5x +14 = y

Substitute this for y in the first equation:

  2.5x -3(3.5x +14) = -13

  2.5x -10.5x -42 = -13

  -8x = 29

  x = -29/8 = -3 5/8

Using this in the formula for y, we get ...

  3.5(-29/8) +14 = y

  -203/16 +14 = y = 21/16 = 1 5/16

5/8 + 4/5 = 9/8 1 17/40 57/40 9/13​
valina [46]

Answer:

57/40

Step-by-step explanation:

Find common denominators, note that what you do to the denominator, you must do to the numerator:

\frac{numerator}{denominator}

First, multiply 5/8 with 5 to both the numerator and denominator:

(5/8) x (5/5) = 25/40

Next, multiply 4/5 with 8 to both the numerator and denominator:

(4/5) x (8/8) = 32/40

Combine the numerators:

(25 + 32)/40 = (57)/40

57/40 is your answer.
