If you mean 2a8b - 5 = x and a2b = 5, then:
2(54) - 5 = x
x = 1350 - 5
x = 1345
3a x 2a =24
Subtract 2a from each side: P - 2a = b ie b = P - 2a
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 --------------------
: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
3a x 2a =24
a = 4
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2
If: 2a+13 = 5a+1 Then: a = 4
Subtract 2a from each side: P - 2a = b ie b = P - 2a
(2a + 1)(4a2 - 2a + 1)
2a - 7 = -9 2a - 7 + 7 = -9 + 7 2a = -9 +7 2a = -2 2a/2 = -2/2 a = -2/2 a= -1
a+a=1 2a=1 a=1/2
depends what 'a' =
Solve the following equation for A : 2A/3 = 8 + 4A
the answer
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 --------------------
