Answer and explanation:

<em>This is what you start off with:</em>

-6f + 13 = 2f - 11

<em>You want to figure out what f equals  </em>-6f + 13 = 2f - 11

<em>Start off by adding 11 to both sides</em>         + 11        + 11

<em>Get the f's alone on one side          </em>   -6f + 24 = 2f

<em>Then add 6f to both sides</em>                + 6f          + 6f

<em>Try to get f alone                                           </em>24 = 8f

<em>Divide by 8 to get f                                 </em>         3 = f

<h2 /><h2>f = 3</h2>

Answer:

f = 3

Step-by-step explanation:

Solve for f:

13 - 6 f = 2 f - 11

Subtract 2 f from both sides:

13 + (-6 f - 2 f) = (2 f - 2 f) - 11

-6 f - 2 f = -8 f:

-8 f + 13 = (2 f - 2 f) - 11

2 f - 2 f = 0:

13 - 8 f = -11

Subtract 13 from both sides:

(13 - 13) - 8 f = -13 - 11

13 - 13 = 0:

-8 f = -13 - 11

-13 - 11 = -24:

-8 f = -24

Divide both sides of -8 f = -24 by -8:

(-8 f)/(-8) = (-24)/(-8)

(-8)/(-8) = 1:

f = (-24)/(-8)

The gcd of -24 and -8 is -8, so (-24)/(-8) = (-8×3)/(-8×1) = (-8)/(-8)×3 = 3:

Answer:  f = 3
