Question

7x-2y=4 What is the variable of y

Answer 1

X is 2, Y is 5

Explanation:

To find the variable y in the equation 7x-2y=4, We need to isolate y on one side of the equation.

Let's start by moving the term with x to the other side of the equation:

7x-2y=4

subtract 7x from both sides:

-2y=-7x+4

Next, we need to isolate y by diving both sidesog the equation by -2:

-2y/-2= (-7x+4)/-2

simplifying:

y = (7/2)x - 2

so, the variable ycan be expressed as (7/2)x - 2.

This means that y depends on x and can be calculated using the given equation. For different values of x, we can substitute them into the equation to find the corresponding value of y. For example, if x = 2, we can substitute it into the equation to find y:

y = (7/2)(2) - 2

y= 7 - 2

y = 5

Therefore, when x is 2, y is 5

I hope this helps! :] Good luck I hope it's right!

Answer 2

x is 2, y is 5.

Explanation:

To find the variable y in the equation 7x - 2y = 4, we need to isolate y on one side of the equation.

Let's start by moving the term with x to the other side of the equation:

7x - 2y = 4

Subtract 7x from both sides:

-2y = -7x + 4

Next, we need to isolate y by dividing both sides of the equation by -2:

-2y / -2 = (-7x + 4) / -2

Simplifying:

y = (7/2)x - 2

So, the variable y can be expressed as (7/2)x - 2.

This means that y depends on x and can be calculated using the given equation. For different values of x, we can substitute them into the equation to find the corresponding value of y. For example, if x = 2, we can substitute it into the equation to find y:

y = (7/2)(2) - 2

y = 7 - 2

y = 5

Therefore, when x is 2, y is 5
