4/3 (15-21x)+x=74

\frac{4}{3} (15 - 21 x) + x = 74

x = - 2

Solution steps

\frac{4}{3} (15 - 21 x) + x = 74

Multiply

\frac{4}{3} (15 - 21 x) : \frac{4 ( - 21 x + 15 )}{3}

\frac{4 ( 15 - 21 x )}{3} + x = 74

Multiply both sides by

3

4 (15 - 21 x) + 3 x = 222

Expand

4 (15 - 21 x) : 60 - 84 x

60 - 84 x + 3 x = 222

Add similar elements:

- 84 x + 3 x = - 81 x

60 - 81 x = 222

Move

60

to the right side

- 81 x = 162

Divide both sides by

- 81

x = - 2

x, 3 x + 2 y - z = 8

C, S = C + RC

x + 6 = - 4

R, P = I^{2} R

9 x - 7 = 10
