This does not sound like an equation. This sounds like evaluating an algebraic expression. 3C means 3 times the value of C (which you have given as 21) then subtract 15. 3 x 21 - 15 = 48

d=3c
3c x 8e = 24
12bc - 4bd - 15xc + 5xd = 4b(3c - d) - 5x(3c - d) = (3c - d)(4b - 5x)
3c-d
Transitive property of equality
It is an algebraic expression that can be simplified to: 27ce
It is the same as: 21ce as an algebraic expression
3c+6=18 3c+6-6=18-6 3c=12 3c÷3=12÷3 c=4
The circumference is tripled.C=pi*d, so pi*(3d) = 3C, where d is diameter and C is circumference.
3c-7 = -4
2y-3c = -1
The solution (not sum) to the equation 21 = 3c + 6 is as follows:21 = 3c + 621 - 6 = 3c + 6 - 615 = 3c3c = 153c/3 = 21/3c = 7
