For A B and C, you just plug in the given number

A
2(15) + 5 = 35
B
4(20) + 2 = 82
C
6(10) + 5 = 65
And for D, you set the equation to 26 and solve for n
3x + 5 = 26 \\ 3x = 21 \\ x = 7
I had to use x instead of n, but for D n=7. :)

|3 + x| = 5<br> Solve for x
bearhunter [10]

Answer:

x = - 8 , x = 2

Step-by-step explanation:

the absolute value function always gives a positive result, however, the expression inside can be positive or negative, , that is

x + 3 = 5 ( subtract 2 from both sides )

x = 2

or

-(3 + x) = 5

- 3 - x = 5 ( add 3 to both sides )

- x = 8 ( multiply both sides by - 1 )

x = - 8
