What is the value of a?
6 ( a + 2 ) + 3 = 3 ( 10 - 3a )

6(a + 2) + 3 = 3(10 - 3a)

First, expand. / Your problem should look like: 
Second, add up 6a + 12 + 3 to get 6a + 15. / Your problem should look like: 
Third, subtract 15 from both sides. / Your problem should look like: 
Fourth, subtract 30 - 9a - 15 to get -9a + 15. / Your problem should look like: 
Fifth, add 9a to both sides. / Your problem should look like: 
Sixth, add 6a + 9a to get 15a. / Your problem should look like: 
Seventh, divide both sides by 15. / Your problem should look like: 

 a = 1

6(a+2)+3=3(10−3a)

(6)(a)+(6)(2)+3=(3)(10)+(3)(−3a)(Distribute)

6a+12+3=30+−9a

(6a)+(12+3)=−9a+30(Combine Like Terms)

6a+15=−9a+30

6a+15=−9a+30

Add 9a to both sides.

6a+15+9a=−9a+30+9a

15a+15=30

Subtract 15 from both sides.

15a+15−15=30−15

15a=15

Divide both sides by 15.

15a/15=15/15

a=1

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
