don't abuse and spam..
-2.8 + ( b - 1.7) = 0.6 times 9.4.
-2.8 + ( b - 1.7) + 2.8 = 5.64 + 2.8
b - 1.7 = 8.44
b - 1.7 + 1.7 = 8.44 +1.7
b = 10.14

-2.8 + ( b - 1.7) = 0.6 times 9.4 first, lets simplify the right hand side 0.6 times 9.4 = 5.64now lets look at the left side, open the brackets, -2.8 + b -1.7 =b - 4.5 so the whole equation is b - 4.5 = 5.64 b = 5.64 + 4.5 b = 10.14

Q: -2.8+(b-1.7)=0.6 times 9.4
1) -2.8+b-1.7 =0.6(9.4)
2) -2.8+b-1.7 =5.64
3) -2.8-1.7+b =5.64
4) b =5.64+2.8+1.7
=10.14

-2.8 + b - 1.7=0.6 times 9.4
-2.8 - 1.7 + b= 5.64
-4.5 + b = 5.64
b= 5.64 + 4.5
b= 10.14
