Show work and check the answer. Thanks so much! Answer by drk(1908) (Show Source):
You can put this solution on YOUR website! Your original equations were:
(i)
(ii)
rewrite (ii) so that a and b are on the same side. We get
(i)
(iii)
multiply (iii) by -2 and eliminate b. then solve for a.
i)
(iii)
sub back into (i) to find b.
Now, we check
(ii) 10 + 4 = 2(4+3) - -> 14 = 14 check
