Using the elimination method, the value of x in the system of equations is calculated as: 8.
<h3>How to Solve a System of Equations by Elimination?</h3>
To solve a system of equations given using the elimination method, do the following:
Multiply 2x - 5y = 1 by 2 and multiply -3x + 2y = -18 by 5 to get the following:
4x - 10y = 2 --> eqn. 1
-15x + 10y = -90 --> eqn. 2
Add
-11x = -88
Divide both sides by -11
x = 8

Add or subtract multiples of 360° to find coterminal angles.
<u>Positive</u>
75° +360° = 435°
75° +2×360° = 795°
<u>Negative</u>
75° -360° = -285°
75° -2×360° = -645°
