You can just do the inverse operation. 39 divied by 10 = 3.9
so 3.9 *10 =39
hope it helped

Answer:21 I used math. way. it is a great app
you do 5-12= -7x-3=21 . in the calculator you don't need the (-s)
Answer:
-4
Step-by-step explanation:
3x-2(6-x)=7x+2(5+x)-6
First, distribute.
3x+ −12+ 2x = 7x + 10 + 2x −6
Combine like terms on each side.
5x − 12= 9x + 4
To solve for x, pick a side to solve. I will solve the right x.
5x - 12 = 9x + 4
-5x -5x
-12 = 4x + 4
Subtract 4 to isolate the variable.
-16 = 4x
Divide 4.
-4 = x
