Question

5a -3a =6a-10 w an explanation please

Answer 1

Answer:

$\frac{5}{2}$

Step-by-step explanation:

5a - 3a = 6a -10  On the left side of the equation, we will combine the like terms.  5a and -3a are like terms.  If I was on a number line and I started at 5 and went 3 spaces towards the negative numbers, where would I be?  2

2a = 6a - 10  I want to get the variable a on only one side of the equation.  I am trying to isolate the variable.  Right now, we have a's on the both the right and left side of the equation.  Let's subtract 6a from both sides of the equation

-4a = -10  The last step is to divide both sides by -4

a = $\frac{10}{4}$

$\frac{10}{4}$÷$\frac{2}{2}$ = $\frac{5}{2}$ or 2.5 or 2$\frac{1}{2}$

Answer 2

Answer:

 a = $\frac{5}{2}$

Step-by-step explanation:

Alright so i´ll explain

you are going to combine 5a and -3a to get 2a

2a= 6a -10

then you are going to subtract 6a from both sides

2a-6a= -10

then combine 2a and -6a to get -4a

-4a= -10

then divide both sides by -4

a=$\frac{-10}{-4}$

and last reduce the fraction to the lowest term, extract and cancel out -2

and the final answer is a = $\frac{5}{2}$

Let me know if you have any doubt, important to be aware of the positive and negative signs
