1076.
1) =2a+6b -14c
2) =0.52x -0.2y -0.52
3) = -0.8a+3.2d-2.4p
4) =1.6ab -1.2ap +0.44ac
5) =mk -29mn+38.9m
6) = - a -3ax+20ay

1077.
1) = -12 -15m+18n
2) =2.8t -0.2z+5y
3) = -0.31x+0.78y - 0.96
4) = -1.05px+0.9py - 0.75pz

1082.
(-8-a)+(a+23)= -8 -a+a+23=23-8=15
(1.3+m)+(-4-m)=1.3+m-4-m=1.3-4= - 2.7
(p-m+k)+(-p+m+k)=p-m+k -p+m+k=k+k=2k
(3.7-2.6+4.2)+(-12.5+2.6-4.2)=3.7 - 2.6+4.2 -12.5+2.6 -4.2=3.7 - 12.5= - 8.8

1083.
(-8.4+a)-(a+14.9)= - 8.4+a - a-14.9= - 23.3
(42 -b) -( -b+36.4)=42 - b + b -36.4=5.6
(m-n)-(-n+m-p)=m-n+n-m+p=p
(-2.2+4.9-c)-(4.9-c-1.3)= -2.2+4.9 -c -4.9+c+1.3= - 0.9
