<span> 10x + 6 = 21
first subtract 6 from both sides of the equation
10x=15
so I believe the answer you are looking for is 10x=15
If you take this one step further and solve for x then you divide both sides of the equation by 10 so then the solution is x=1.5

First step: multiply the 5(x3) and it will give you x15 or most commonly written as 15x. you should now have 15x-(-20).
Second step: since you cannot subtract -20 from 15x because it has a variable, the final answer is just 15x-(-20), or 15x+20.
12 different combinations because 4 times 3 equals 12.
This is what i did to get the answer.
