5........is this really a question? when b=5, then b=5
3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28
We are given that a + b = -7 and b = 10 Therefore a +10 = =7 Subtract 10 from each side So a + 10 - 10 = -7 + 10 Which simplifiesn to a = 10 - 7 So a = 3
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.
-2
a( 10 ) - b( 5 ) = 5 ?

3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28
y = (3 X 8) - 5 = 21.
a = 1
Unfortunately, limitations of the browser used by WA means that we cannot see some symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Do you want the value of a/b or a+b or what?
Whan a = 2 and b = 6, 5a + 2b = 5*2 + 2*6 = 10 + 12 = 22
If: b/5+b/3 = 10 then b works out as 18.75
