c = 6 and d = 7
If a=b and c=d then (a+c)=(b+d) ? This is proved very simply by the direct application of perhaps the most fundamental statement in all of Algebra: "If equals are added to equals, the sums are equal."

2+21=23 or 3+15=18 ok . ans:h-c-d-d-g-g 45+585*=474 552++
Divide both sides by 4: c = d/4
the answer is a
C = D C = 10 utils, and D = 10 utils
They all equal each other. a = b = c = d = e e = a e = b e = c e = d e = e
As A/B=C/D , So B=(A*D)/C
c = 6 and d = 7
1cm equals 10mm; 2cm equals 20mm. Metric is so easy, it's all in tens!
If: a = b+c+d Then: c = a-b-d
c
6d = c Divide both sides by 6: d = c/d
If a=b and c=d then (a+c)=(b+d) ? This is proved very simply by the direct application of perhaps the most fundamental statement in all of Algebra: "If equals are added to equals, the sums are equal."
