Zorluk: KolaySimplifying Algebraic Expressions

Which simplified algebraic expression corresponds to each unsimplified expression? Match each item on the left with its correctly simplified equivalent on the right.

  • 4x+3x−54x + 3x - 57x−57x - 5
  • 2(3x+4)2(3x + 4)6x+86x + 8
  • 9x−4x+29x - 4x + 25x+25x + 2
  • 3(x−2)+53(x - 2) + 53x−13x - 1

Cevap

The correct pairings are: 4x+3x−54x + 3x - 5 matches with 7x−57x - 5; 2(3x+4)2(3x + 4) matches with 6x+86x + 8; 9x−4x+29x - 4x + 2 matches with 5x+25x + 2; and 3(x−2)+53(x - 2) + 5 matches with 3x−13x - 1.
Each expression is correctly matched to its simplified equivalent by strictly applying the distributive property to eliminate any grouping symbols, followed by combining like terms (terms with identical variables) and grouping constants.

Adım Adım Çözüm

1
Simplify the first expression, 4x+3x−54x + 3x - 5.
7x−57x - 5
Combining the like variable terms (4x4x and 3x3x) gives 7x7x. The constant −5-5 remains unchanged.
2
Simplify the second expression, 2(3x+4)2(3x + 4).
6x+86x + 8
Applying the distributive property multiplies each term inside the parentheses by 22.
3
Simplify the third expression, 9x−4x+29x - 4x + 2.
5x+25x + 2
Combining the like variable terms (9x9x and −4x-4x) gives 5x5x. The constant 22 remains unchanged.
4
Simplify the fourth expression, 3(x−2)+53(x - 2) + 5.
3x−13x - 1
Distributing the 33 yields 3x−63x - 6. Combining the constant terms (−6-6 and 55) results in −1-1.
