Question

If y=3x and 2x−4y=3 , then x=

Answer 1

Answer:

x = -3/10

Step-by-step explanation:

Solve for x by substituting y = 3x into the other equation:

2x - 4y = 3

2x - 4(3x) = 3

Simplify and solve for x:

2x - 12x = 3

-10x = 3

x = -3/10

So, x = -3/10

Answer 2

Answer:

$x=-\frac{3}{10}$

Step-by-step explanation:

2x - 4y = 3

y = 3x

2x - 4(y = 3x) = 3

2x - 4(3x = 3)

2x - 12x = 3

- 10x = 3

- 10x ÷ - 10 = 3 ÷ - 10

$x=-\frac{3}{10}$
