Answer:
y = negative x.
y = three-halves x minus 5
Step-by-step explanation:
Let y and x be the numbers and let x be the bigger number and let y be the smaller number.
From the question,
The sum of the two numbers is equal to zero. This is written as
x + y = 0
y = 0 — x
y = — x
Twice the smaller number is written as: 2y
Three times the bigger number is written as: 3x
But we were told that twice the smaller number subtracted from 3 times the larger number is 10. This is illustrated below:
3x — 2y = 10
Make y the subject, we have
3x — 10 = 2y
Divide both side 2
y = (3x — 10)/2
y = 3x/2 — 5.
The expression are
y = — x
y = 3x/2 — 5.
