Answer:
3a - 2b - c + 16 = 23
Explanation:
so we want to write an equetion which containe a, b and c so we have given
4a - 2b = 10 and a + c = 3
so we are going to differentiate 10 to 7 + 3 it will be
4a - 2b = 10
4a - 2b = 7 + 3 ...then we insert a + c in place of 3 b/c they are equal
4a - 2b = 7 + a + c .... we take to the left side of the equal sighn
4a - a - 2b - c = 7
3a - 2b - c = 7
thrn if we want to write the equetion =23 we add 16 both side 3a - 2b - c + 16 = 23 .
