Answer:
The numbers are 18 and 91
Step-by-step explanation:
You can translate the information to two equations:
<em>a value 5 times a smaller number is 1 less than a larger number</em>
5a = b - 1
<em>their difference is 73</em>
b - a = 73
Then you should merge one equation into the other, thereby eliminating one variable. You can do this any way you want. I choose to rewrite the first equation as:
b = 5a + 1
Now I can write 5a+1 in the second equation at the place where b was:
5a + 1 - a = 73
It is now an equation with only one variable, solve by simplifying
4a = 72
a = 18
Now b can be found using b = 5a + 1
b = 91
Step-by-step explanation:
5 - n/2 = 12
10/2 - n/2 = 12
n = (12 × (-2)) + 10
n = (-24) + 10
n = <u>-1</u><u>4</u>
Let's prove it :
Conclusion :
5 - n/2 = 12
5 - (-14/2) = 12
and
n = -14
The answer should be 140.9%
1.) Solving for x: x= -(3y/2) +5
solving for y= -(2x/3)+3 1/3
2.)solving for x: x= 10y/3+5
solving for y: y=3x/10 - 1 1/2
