Answer 1

1) 15,2х+8,3+4,6х+7,5=19,8х+15,8=19,8×0,5+15,8=9,9+15,8=25,7

2) 19,8у-12,6у+4,37+3,1у=10,3у+4,37=10,3×2,1+4,37=21,63+4,37=26

3)(6,5х-2,7х)+(13,4х-5,2х)=3,8х+8,2х=12х=12×0,7=8,4

Answer 2

1. 15.2x + 8.3 + 4.6x + 7.5 = 15.2x+4.6x+8.3+7.5 = 19.8x+15.8=19.8*0.5+15.8 = 9.9+15.8 = 25.7
2. 19.8y - 12.6y +4.37 + 3.1y= 10.3y+4.37 = 10.3*2.1+4.37 = 26
3. (6.5x-2.7x)+(13.4x-5.2x) = 12x = 12*0.7 = 8.4
