The first step in solving the equation 2a - 4( a - 5 ) = 10 is to distribute 4 to both terms inside the parentheses.

The first step in solving the equation 2a - 4( a - 5 ) = 10 is to distribute 4 to both terms inside the parentheses.

This gives us 2a - 4a + 20 = 10.

Next, we can simplify the equation by combining like terms. 2a - 4a simplifies to -2a.

So the equation becomes -2a + 20 = 10.

To isolate the variable a, we need to get rid of the constant 20 on the left side.

We can do this by subtracting 20 from both sides of the equation.

The first step in solving for a in the equation would be:

1.distribute -4 to a and -5, then:

2a-4a+20=10

Now the next steps in solving for a:

2.Add 2a and -4a :

-2a+20=10

3.Substract 20 to both sides

-2a+20-20=10-20

then:

-2a= -10

4.Finally, divide both sides by -2


(-2a)/(-2)=(-10)/(-2)=5

then, a=5
