To solve this, isolate x.
first, add 10 to both sides.
this will leave you with
2a + 15 = a
Then, subtract 2a from both sides.
This will leave you with
15 = -a
Therefore,
-15 = a

Subtract 2a from each side: P - 2a = b ie b = P - 2a
If fx equals 2x plus 5 find f a plus h minus f a divided h?
It is [(2a+2h+5) - (2a+5)]/h = 2h/h = 2
Does a plus b plus 2 plus 3 equals 2a plus 3b?
a+b+2+3=5+a+b
Given the formula times equals 2a b plus 7find times if a equals 3and b equals 5?

How do you solve b equals 2a plus 11 and a plus b equals 5 by substitution?
b = 2a + 11a + b = 5 which is b = 5 - atherefore2a + 11 = 5 - a (which is b = b)2a + a = - 11 + 53a = - 6a = - 2looking at first equation substitute - 2 for a:b = 2a + 11b = 2*(- 2) + 11b = - 4 +11b = 7to check:a + b = 5- 2 + 7 = 5
