Question

solve the following pair of simultaneous linear equation 2 X + 3 Y = 28 and 2x equals to 2 + 3 y ​

Answer 1

Answer:

1. 2x + 3y = 28 equation
2. 2x = 2 + 2y
3. 2x - 3y = 2 equation

Add both equation

• 2x + 3y = 28

+ 2x - 3y = 2

4× - 0 = 48

• 4x = 48
• x = 48 / 4
• x = 12

Putting x value in 2 equation

• 2 × 12 - 3y = 2
• 24 - 3y = 2
• -3y = 2 - 24
• -3y = -22
• -y = -22 / 3
• y = 22 / 3
