Answer:

x =
(23)/(8) or 2
(7)/(8)

Explanation:

1. Add the numbers

10 + 2 = 12

5x+12+11x = 58

2. Combine like terms

5x + 11x = 16x

16x+12 = 58

3. Subtract 12 from both sides

16x + 12-12 = 58-12

x =
(23)/(8)

Simplifying
5x + 10 + 11x + 2 = 58

Reorder the terms:
10 + 2 + 5x + 11x = 58

Combine like terms: 10 + 2 = 12
12 + 5x + 11x = 58

Combine like terms: 5x + 11x = 16x
12 + 16x = 58

Solving
12 + 16x = 58

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12' to each side of the equation.
12 + -12 + 16x = 58 + -12

Combine like terms: 12 + -12 = 0
0 + 16x = 58 + -12
16x = 58 + -12

Combine like terms: 58 + -12 = 46
16x = 46

Divide each side by '16'.
x = 2.875

Simplifying
x = 2.875
