Y= 3/4x
5/2x + 2y = 5

x = 5/4

y = 15/16

Step-by-step explanation:

substitute 3/4x for 'y' in the 2nd equation

5/2x + 2(3/4x) = 5

multiply each side by 4 to eliminate fractions:

10x + 6x = 20

16x = 20

x = 20/16 or 5/4

y = 3/4 · 5/4

y = 15/16

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
