A equals 20.
3a plus 5 equals 5a plus 3?
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
Does a plus b plus 2 plus 3 equals 2a plus 3b?
a+b+2+3=5+a+b
What is the solution of a 5a-5 equals 7 plus 2a?
5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
A equals one-half h b plus c in parentheses solve for b?
:a = .5(hb+c) :2a = hb+c :2a−c = hb :(2a−c)/h = b
What is 2a plus 5 equals 45?

2a+5a=3 7a=3 a=3/7 or .4286
3a plus 5 equals 5a plus 3?
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
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
2a-4b plus 4b-6a equals a plus b?
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
