Supplementary angles add up to 180°, meaning that the supplement of 25° can be added to it to get 180°.
To find the supplement, subtract 25° from 180°.
180° - 25° = 155°
3x + 6(2x - 5) = 3x - 3
First, take out '3x' on both sides.
Second, divide both side by '6'.
Third, find the GCF of 3 and 6.
The GCF is 3.
Fourth, divide the numerator by the GCF.
÷
Fifth, divide the denominator by the GCF.
÷
Sixth, rewrite the fraction in simplest form.
Seventh, add '5' to both sides.
Eighth, make the denominators the same.
Ninth, simplify so that the denominators are the same.
Tenth, combine the denominators.
Eleventh, subtract '-1 + 10' to get '9'.
Twelfth, divide both sides by '2'.
Thirteenth, multiply '2 × 2' to get '4'.
