Can I have the steps and answers pls so I can understand thx

1. first, we have to get rid of the fractions. because fractions are essentially division, we use the opposite function to “undo” it. in this case, multiply each side by 2 to get:

3x + 1 = 10
then subtract 1
3x = 9
divide by 3
x = 3

2. distribute the left side to get

x^2 + 2x -3 = x^2 - 2x + 13
subtract x^2 from each side
2x -3 = -2x + 13
add 2x to each side
4x -3 = 13
add 3
4x = 16
divide by 4
x = 4

3. to get rid of the square root sign, square each side to get:

2x + 5 = 10^2
2x + 5 = 100
subtract 5
2x = 95
divide by 2
x = 95/2

It is 7 because it is the absolute value
