b = y - mx.
If: a = b+c+d Then: c = a-b-d
That factors to (a + 1)(a + b) a = -1, -b b = -a
A = 1, B = 9
you can't get a value for either a or b from just the information you have given - you can only get an expression for what a is in terms of b and vice versa; a=3+b b=a-3
y = mx + b y - mx = b
b = 14
All you need to do is substitute the given values of a and c into the equation, then solve for c: a2 + c2 = b2 102 + 302 = b2 100 + 900 = b2 b2 = 1000 b = √1000 b = 10√10
b = -6
15+b = 23 Subtract 15 from both sides b = 8
5b + 3 = 10 - 3 - 3 5b = 7 5b/5 7/5 b= 1.5 There you go !
If: a = 2b+c Then: a-c = 2b And: b = (a-c)/2
it can be any number since A and B (5+5 3+7 -4+14 etc) since both variables in this case. However if they give the value of B you can solve it.
12 = -4/7 * -2 + b 12 = 8/7 + b 10 6/7 = b

No it can't
Subtract 2a from each side: P - 2a = b ie b = P - 2a
b+9=2 sbtract nine both sides b=2-9 b=-7
