3a + 5b - 6a - 9b = -3a - 4b
What is the solution of -2a plus 3a plus 5b
-b+5b-2b=2b
Let a + bi be the reciprocal. So (a + bi)(2 - 5i) = 1 (a + bi)(2 - 5i) = 2a - 5ai + 2bi + 5b = (2a + 5b) + (2b - 5a)i Therefore 2a + 5b = 1 and 2b - 5a = 0. Solving the simultaneous equations, we find that a = 2/29 and b = 5/29. So the reciprocal of 2 - 5i is 2/29 + 5i/29.
It IS expanded.
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
5b
It is: 5a+5b
It is: 5(a+b)
10a + 5b
3a + 5b - 6a - 9b = -3a - 4b
The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.
it think ot is 5(a+b)
5ab-2ab+4a-b+5b = 3ab+4a+4b
5a2 - 20ab - 25b2 = 5(a2 - 4ab - 5b2) = 5(a2 - 4ba - 5b2) since -5b*b = -5b2 and -5b + b = -4b, then = 5(a - 5b)(a + b)
Your equation cannot be solved. So we simplify using fun algebra! 4b + b = 5b
