How do you find "a" in -10+a=6a-7a please help I do not know how to find what the answer is.
Sunny_sXe [5.5K]
-10 + a = 6a - 7a

Rearrange the left hand side

a - 10 = 6a - 7a

Simplify 6a - 7a

a - 10 = -a

Add a on both sides

2a - 10 = 0

Add 10 on both sides

2a = 10

Divide by 2 on both sides

a = 5

Step-by-step explanation:

a. more people on average lived longer lives. (explanation)

b. self explanatory I guess, my answer pretty much explained it.

c. life span of US citizens does not effect the children population. I guess you could say people lived longer lives to have more children, so possibly the number of children could have increased.
