Hello!!
Isolate the variable by dividing each side by factors that don't contain the variable.
Your answer is 12.5.
Hope that you pass your test!!
0.4(3b + 10) = 19
First: Distribute
0.4 x 3b = 1.2b
0.4 x 10 = 4
1.2b + 4 = 19
Second: Subtract 4 from both sides
+ 4 - 4 cancels out
19 - 4 = 15
1.2b = 15
Third: Divide 1.2b on both sides
1.2b/1.2 cancels out
15/1.2 = 12.5
Answer: b = 12.5
Hope this Helps!!
