Answer 1

а + 2а + 3b = 3a + 3b

4s + s + 3r + s = 6s + 3r

3x + 2y + x + 5y = 4x + 7y

5q + p + 2p + 6q = 11q + 3p

10a + 2c + a + 3c = 11a + 5c

2a + 5a + 4b + 2b = 7a + 6b

7f + g + 3g + 3f = 10f + 4g

10p + 4q + q + 2q = 10p + 7q

6p + 2t + 5p + 4t = 11p + 6t

Answer 2

№12.

a+2a+3b=3a+3b=3(a+b)

4s+s+3r+s=6s+3r=3(2s+r)

3x+2y+x+5y=4x+7y

5q+p+2p+6q=11q+3p

10a+2c+a+3c=11a+5c

2a+5a+4b+2b=7a+6b

7f+g+3g+3f=10f+4g=2(5f+2g)

10p+4q+q+2q=10p+7p

6p+2t+5p+4t=11p+6t
