Answer:
the original number is 7
Step-by-step explanation:
7•4 = 28
28+12=40
1. Answer is 14.
you first do 8x6 cause of BEDMAS, which is 48. then subtract 12, which gives you 36. then subtract 36 from 50 because 50 is the total amount it should be on both sides.
50 - 36 = 14
2. Answer is 8
5x3 is 15, + 2 is 17. then 20 - 17 gives you 3. you then have 24 divided by a number, and that number is 8 because 24 divided by 8 gives you three
An equation without exponents and two variables, is typically a straight line. All the points on the line with integer coordinates are solutions of the equation. Since x and y have to be positive as well, there aren't that many solutions.
Let's see where the line crosses the x-axis, it is where y=0:
x/0.5 + 0 = 18, so x=9 at the intercept. y=0 there, so this is a point on the line, but not a solution to the question (y was supposed to be positive).
Possible values for x are thus limited to 1,2,3,4,5,6 and 7. You can try them all (ie., solve the equation with them) and see for which x values the y is also positive and integer.
You will find that x=4, y=2 is the only pair that satisfies these conditions.
It's like simple math but the sign of the answer would be the opposite.
