Question

simultaneous equation 2x=3y ; 2x-3y=60​

Answer 1

Answer:

♦ x = 0

♦ y = 0

Step-by-step explanation:

To solve:

The given simultaneous equation:

2x = 3y ; 2x - 3y = 60

Solution:

2x = 3y

x = 3y/2

As we are already provided with this ( 2x = 3y ), so we will simply substitute the value of x in the second equation which we are given to find the value of y and after that we will substitute the value of y in ( 2x = 3y ) to find the value of x. In such way to can easily find the value of both the variables and solve the given simultaneous equation.

• 2x - 3y = 60

Substituting the value of x in the given equation, we have:

• 2( 3y/2 ) - 3y = 60
• 2( 3y ) - 6y = 120
• 6y - 6y = 120
• 0 = 120

Therefore, the value of y = 0

Then solve for x.

• 2x = 3y
• 2x = 3 × 0
• 2x = 0
• x = 0/2
• x = 0

Therefore, x = 0
