Simplify (3x − 11y) − (17x + 13y) and choose the right answer.
पर्याय
7x − 12y
−4x − 54y
−3 (5x + 4y)
−2 (7x + 12y)
उत्तर
−2 (7x + 12y)
Explanation:
= −11y − (17x + 13y)
= 3x − 11y − 17x − 13y
= (3x − 17x) + (−11y − 13y)
= −14x + (−24y)
= −14x − 24y
= −2 (7x + 12y)
So, the correct option is −2 (7x + 12y).
