Step-by-step explanation:
A. 5x=12x-14
you will simplify the equation to the form, which is simple to understand
5x=12x-14
We move all terms containing x to the left and all other terms to the right.
+5x-12x=-14
We simplify left and right side of the equation.
-7x=-14
We divide both sides of the equation by -7 to get x.
x=2
B. 5B+12=BB=28
you will move all terms to the left:
.5B+12-(BB)=0
you will move all terms containing B to the left, all other terms to the right
.5B-BB=-12
Alright! In order to solve this problem you need to know your keywords:
Sum = To add
Difference = Subtract
Product = To multiply
So! When it asks for the sum of 24 and 7 you add them:
24 + 7 = 31
The difference of 18 and 6:
18 - 6 = 12
The find the product of these two you simply multiply:
12 x 31 = 372!
