There exists a trigonometric identity which states that,
                  sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
                                 sin (57° - 13°) = sin 44°

- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define Systems</u>
16x + 14y = 8
-63x - 14y = 133
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine 2 equations:                    -47x = 141
- Divide -47 on both sides:               x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation:                    16x + 14y = 8
- Substitute in <em>x</em>:                                     16(-3) + 14y = 8
- Evaluate multiplication:                       -48 + 14y = 8
- Add 48 on both sides:                        14y = 56
- Divide 14 on both sides:                      y = 4
