Dos anyone know how much a is 2(a+7)-7=9

a =1

Step-by-step explanation:

2(a+7)-7=9

Add 7 to each side

2(a+7)-7+7=9+7

2(a+7)=16

Divide by 2

a+7 = 16/2

a +7 = 8

Subtract 7

a+7-7 = 8-7

a = 1

Step-by-step explanation:

So we have the equation:

And we want to find the value of a.

So, add 7 to both sides. The left side cancels:

Divide both sides by 2:

Subtract 7 from both sides:

Therefore, the alue of a is 1.

And we're done!
