3(7r-2)=21r-6

3 (7 r - 2) = 21 r - 6

True for all r

Solution steps

3 (7 r - 2) = 21 r - 6

Expand

3 (7 r - 2) : 21 r - 6

21 r - 6 = 21 r - 6

Move

6

to the right side

21 r = 21 r

Move

21 r

to the left side

0 = 0

Both sides are equal

True for all r

\frac{8}{5} a = - 6

9 = - 5 - 2 n - 5 n

\frac{x + 1}{3} + \frac{x + 2}{7} = 5

h, s = 2 π r^{2} + 2 π r h

29 = 1 + \frac{1}{2} x
