18-6a=4a-4(a+3)

18 - 6 a = 4 a - 4 (a + 3)

a = 5

Solution steps

18 - 6 a = 4 a - 4 (a + 3)

Expand

- 4 (a + 3) : - 4 a - 12

18 - 6 a = 4 a - 4 a - 12

Add similar elements:

4 a - 4 a = 0

18 - 6 a = - 12

Move

18

to the right side

- 6 a = - 30

Divide both sides by

- 6

a = 5

5 - 3 x = 6 x - 2

35 t + 70 (7 - t) = 385

(4 - 2^{2} + 5) w = 25

\frac{3}{4} x = \frac{π}{2}

s + (2 s) + (s + 3) = 55
