Question

solve 2x-y=2 and 4x-y=4​

Answer 1

Answer:

Step-by-step explanation:

Given: 2x-y=2----------------(1)

4x-y=4----——------(2)

From 1 we have

2x-y=2

y=2x-2-------(3)

Substitute value of y from 3 in 2.

4x-(2x—2)=2

4x-2x+2=2

2x+2=2

2x=4

X=1

Substitute in 1

2(1)-y=2

2-y=2

Y=4

Therefore x=1, y=4.

Answer 2

Answer:

x = 1 and y = 0

Step-by-step explanation :

Given that two equations -

2x - y = 2    ---------------------------------(1)

4x - y = 4    ---------------------------------(2)

Solve equation 1 for y :-

y = 2x - 2

y intercept is  = -2; So, coordinate is = (0 , -2)

Now find the x-intercept. In order to find the x-intercept we put y = 0 in given equation.

0 = 2x - 2

x = 1

So, coordinate is = (1,0)

Solve equation 2 for y :-

y = 4x - 4

y intercept is  = -4; So, coordinate is = (0 , -4)

Now find the x-intercept. In order to find the x-intercept we put y = 0 in given equation.

0 = 4x - 4

x = 1

y = 0
