4х - 16 = 6 * (3 + х)
4х - 16 = 18 + 6х
4х - 6х = 18 + 16
- 2х = 34
х = 34 : (- 2)
х = - 17
-------------------------------------------
4 * (- 17) - 16 = 6 * (3 + (- 17))
- 68 - 16 = 6 * (- 14)
- 84 = - 84

Answer:
S1) False. 2³ is 2 × 2 × 2 which is <u>8, not 6.</u>
S2) False. ( 2x / 3y ^ (2) ) ^ (3) =
( (2x) ^ (3) / ( (3y) ^ (2) ) ^ (3) ) = (2)³ × (x)³ / (3)³ × (y²)³ = 8 × x³ / 27 × y<u>⁶</u> = 8x³ / 27y<u>⁶</u><u>.</u>
<u>i.e </u><u>(</u><u>a^</u><u>b</u><u>)</u><u>^</u><u>c</u><u> </u><u>=</u><u> </u><u>a^</u><u>(</u><u>b </u><u>×</u><u> </u><u>c)</u><u>.</u>
S3) True.
S4) True.
S5) False. x^(-3) = 1 / x^(3) ≠ 1 / 3x
3t + 20 = 7t
20 = 7t - 3t
20 = 4t
20/4 = t
