Answer:
a = 9
Step-by-step explanation:
2(a + 7) = 5a - 13
We want to bring a to one side, I will choose to bring it to the right
First, expand the bracket by multiplying 2 with a + 7
2a + 14 = 5a - 13
Bring the -13 to the left by adding 13 to both sides
2a + 14 + 13 = 5a - 13 + 13
Simplify
2a + 27 = 5a
Bring the 2a to the right by subtracting 2a from both sides
2a - 2a + 27 = 5a - 2a
Simplify
27 = 5a - 2a
27 = 3a
Bring the 3 to the left by dividing both sides by 3
27÷3 = a
Simplify
a = 9
Answer:
(5,-2)
Step-by-step explanation:
6+4=10

12222x333=4069926 is the answer
Answer:the third one
Step-by-step explanation: so if you are doing that, it is simple. If it is the power of something, then you go left to multiply, and go right to divide. Then, you will get your answer, but when you are done with that, add then subtract . There, you will find your new answer.
