Answer 1

(1) 4a + 3a

ㅤ= (4 + 3)a

ㅤ= 7a

(2) 8a – 6a

ㅤ = (8 – 6)a

ㅤ = 2a

(3) -2x – 4x

ㅤ = (-2 – 4)x

ㅤ = -6x

(4) 9a – 10a

ㅤ = (9 – 10)a

ㅤ = -a

(5) -2x + 7x

ㅤ = (-2 + 7)x

ㅤ = 5x

(6) 4a + 6 + a + 3

ㅤ = (4 + 1)a + 6 + 3

ㅤ = 5a + 9

(7) -5x + 10 + 3x – 9

ㅤ = (-5 + 3)x + 10 – 9

ㅤ = -2x + 1

(8) 7 – 8a – a + 6

ㅤ = (-8 – 1)a + 7 + 6

ㅤ = -9a + 13

(9) 2,7x – 1,4x

ㅤ = (2,7 – 1,4)x

ㅤ = 1,3x

(10) ⅔y + ⅚y

ㅤㅤ= ⁴⁄₆y + ⅚y

ㅤㅤ= ⁹⁄₆y

ㅤㅤ= ³⁄₂y
