Question

solve x and y the equations are y=2x+1and y=4x_1​

Answer 1

Answer:

y=3x

y=4x

Explanation:

y=2x+1=2x

y=4x_1=4x

Answer 2

Answer:

x=1, y=3

Explanation:

y=2x+1  ----(1)

y=4x-1​  ----(2)

Substitute the value of y from euqation 2 into equation 1

Therefore, we get:

4x-1 = 2x+1

4x-2x-1 = 1

4x-2x = 1+1

2x = 2

x = 2/2

x = 1

Now substitute the value of x=1 in equation 1

Therefore, we get:

y = 2x+1

y = 2(1)+1

y = 2+1

y = 3
