(2a + 1)(4a2 - 2a + 1)
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2
a = 4
depends what 'a' =
If: 2a+13 = 5a+1 Then: a = 4
a+a=1 2a=1 a=1/2
Solve the following equation for A : 2A/3 = 8 + 4A
a + a + a - 2a = 3a - 2a = a
2a + 2b = c subtract 2a from both sides 2a - 2a + 2b = c - 2a 2b = c - 2a divide both sides by 2 (2/2)b = (c - 2a)/2 b = (c - 2a)/2 --------------------
2a+2a-7b+7b =4a
:a = .5(hb+c) :2a = hb+c :2a−c = hb :(2a−c)/h = b
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
