Answer:
4060
Step-by-step explanation:
Subtracting 4 from both sides of the equation ¹/₂x = -¹/₂ gives us; ¹/₂x - 4 = -¹/₂ - 4
<h3>How to use subtraction property of equality?</h3>
We want to simply the expression which is;
¹/₂x = -¹/₂
Now, when we subtract 4 from both sides, it means we are using subtraction property of equality which states that subtracting the same value from both sides of an equation makes the equation still to be equal. Thus, we have;
¹/₂x - 4 = -¹/₂ - 4

Answer:
41
Step-by-step explanation:
Original number xy
x + y = 5
3 (10y + x) -1 = 10x + y
30y + 3x -1 = 10x + y
7x - 29y + 1 = 0
x = 5 - y
7 (5-y) - 29y +1 = 0
35 - 7y - 29y +1 = 0
36 - 36y = 0
36y = 36
y = 1
x = 5-1 = 4
Original number: 41
check: 4+1=5
3 x 14 - 1 = 42 -1 = 41
