Question

How to solve simultaneous equation y=6-3x; y=4-x​

Answer 1

Given Equation

⇒y = 6 - 3x                        (i)

⇒y = 4 - x                         (ii)

To find the value of x and y

Now using substitution method

⇒y = 6 - 3x                        (i)

⇒y = 4 - x                         (ii)

Now put the value of y on (ii)eq

⇒6 - 3x = 4 - x

⇒6 - 4 = - x + 3x

⇒2 = 2x

⇒x = 2/2

⇒x = 1

Now put the value of x on (i)eq

⇒y = 6 - 3x            (i)

⇒y = 6 - 3(1)

⇒y = 6 - 3

⇒y = 3

Answer

⇒x = 1 , y = 3

Answer 2

Step-by-step explanation:

Given Equation

⇒y = 6 - 3x                        (i)

⇒y = 4 - x                         (ii)

To find the value of x and y

Now using substitution method

⇒y = 6 - 3x                        (i)

⇒y = 4 - x                         (ii)

Now put the value of y on (ii)eq

⇒6 - 3x = 4 - x

⇒6 - 4 = - x + 3x

⇒2 = 2x

⇒x = 2/2

⇒x = 1

Now put the value of x on (i)eq

⇒y = 6 - 3x            (i)

⇒y = 6 - 3(1)

⇒y = 6 - 3

⇒y = 3

Answer

⇒x = 1 , y = 3
