Well, honey, if you take a number and add 2 to it, you've got yourself a number that's been increased by 2. It's as simple as that, no need to overcomplicate things. So go ahead, add those two little digits and see what you come up with.
The number is 2
4*(n + 2)
X-5^2
2
Let the number be x and so the algebraic expression is: 6x+2
The number is 2
4*(n + 2)
X=2
X-5^2
(x/2) + 50
The number will be increased by 1.5 as for example 2+1.5 = 3.5
7x + 2
18 + n*(-2) = 18 - 2n
28 .5 x 28= 14 14 + 2= 16
80 + n^2
2n+5
If the number is x then: 4x+10 = -2 and so the value of x is -3
