Question

0,7+0,3(x+2)=0,4(x-3)

Answer 1

$0.7 + 0.3(x + 2) = 0.4(x - 3) \\ 0.7 + 0.3x + 0.6 = 0.4x - 1.2 \\ 0.3x - 0.4x = - 1.2 - 1.3 \\ - 0.1x = - 2.5 \\ x = - 2.5 \div ( - 0.1) \\ x = 25 \div 1 \\ x = 25$

Answer 2

0.7 + 0.3х+ 0.6 = 0.4х - 1.2

0.3х-0.4х= -1.2-0.7-0.6

-0.1х = -2.5

х= -2.5/-0.1

х= 25
