Question
Solve the system of equations: x - 2y = 0, 3x + 4y = 20
✓
Answer
The given equations are as follows:
x - 2y = 0 ....(i)
3x + 4y = 20 ...(ii)
On multiplying (i) by 2, we get
2x - 4y = 0 ...(iii)
On adding (ii) and (iii), we get
4 - 2y = 0
⇒ 4 = 2y
⇒ y = 2
Hence, the required solution is x = 4 and y = 2.
x - 2y = 0 ....(i)
3x + 4y = 20 ...(ii)
On multiplying (i) by 2, we get
2x - 4y = 0 ...(iii)
On adding (ii) and (iii), we get
4 - 2y = 0
⇒ 4 = 2y
⇒ y = 2
Hence, the required solution is x = 4 and y = 2.
