(a) Construct 3 equations starting with x = 2 |
(b) Construct 3 equations starting with x = -2 |
Answer:
(a) x = 2 Multiplying both sides by 5, we get 5x - 10 ...(i) Subtracting 3 from both sides, 5x - 3 - 10 - 3 5x - 3 =7 ..(ii) Dividing both sides by 2, we get \[\frac{5x}{2}-\frac{3}{2}=~\frac{7}{2}\] ?(iii) (b) x = -2 Subtract 2 from both sides, x ? 2 = - 2 - 2 x ? 2 = - 4 ...(i) Again, x = - 2 Multiplying by 6, \[6x=-2\times 6\] 6x -12 Subtracting 12 from both sides, 6x - 12 = - 12 - 12 6x-12--24 ...(ii) Adding 24 to both sides, 6x - 12 + 24 = - 24 + 24 6x+12=0 ...(iii)
