(c + 3) + -2c + -1(1 + -3c) = 2
Reorder the terms:
(3 + c) + -2c + -1(1 + -3c) = 2
Remove parenthesis around (3 + c)
3 + c + -2c + -1(1 + -3c) = 2
3 + c + -2c + (1 * -1 + -3c * -1) = 2
3 + c + -2c + (-1 + 3c) = 2
Reorder the terms:
3 + -1 + c + -2c + 3c = 2
Combine like terms: 3 + -1 = 2
2 + c + -2c + 3c = 2
Combine like terms: c + -2c = -1c
2 + -1c + 3c = 2
Combine like terms: -1c + 3c = 2c
2 + 2c = 2
Add '-2' to each side of the equation.
2 + -2 + 2c = 2 + -2
Combine like terms: 2 + -2 = 0
0 + 2c = 2 + -2
2c = 2 + -2
Combine like terms: 2 + -2 = 0
2c = 0
Solving
2c = 0
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Divide each side by '2'.
c = 0

Answer:
For example, [latex]\text{60%}=\frac{60}{100}[/latex] and we can simplify [latex]\frac{60}{100}=\frac{3}{5}[/latex]. Since the equation [latex]\frac{60}{100}=\frac{3}{5}[/latex] shows a percent equal to an equivalent ratio, we call it a percent proportion.
