Kunci Jawaban Matematika Kelas 7 Halaman 77-81 Kurikulum Merdeka Menyederhanakan Bentuk Linear

= 3/5x + 2/5x - 2/3 + 1/3

= x - 1

Soal nomor 2

(1) (7x + 2) - (3x - 1)

(2) (x - 8) - (2x - 5)

(3) (-4a + 9) - (a + 3)

(4) (5a + 6) - (-2a + 6)

(5) (7 - x) - (2x + 8)

(6) (⅓x - 2) - (½x - 5)

Kunci Jawaban:

(1) = (7x + 2) - (3x - 1)

= (7x + 2) + (-3x + 1)

= 4x + 3

(2) = (x - 8) - (2x - 5)

= (x - 8) + (-2x + 5)
