Answer:

$x = y - 6.4$

Steps :

1. Create an equation

If x-4=0 and y-10.4=0, then x - 4 = y - 10.4

$x - 4 = y - 10.4$

2. Isolate variable X by adding 4 to both sides

$x = y - 6.4$

3. (Optional) Check Answer by plugging given values into the equation

$(4) = (10.4) - 6.4$

4 = 4 is a true statement

Answer:

A) y will increase by 4 unit.

B) y will decrease by 20 units

Step-by-step explanation:

Given equation that shows relation between x and y.

$y=4x-3$

A) If x is increased by 4 units

New value of y = $4(x+1)-3$

$=4x+4-3$

$=4x+1$

So, change in y = new value of y- original value of y

$=4x+1-(4x-3)$

$=4x+1-4x+3$

$=4$

Thus, the value of y will be increased by 4 units.

B) If x is decreased by 5 units

New value of y = $4(x-5)-3$

$=4x-20-3$

$=4x-23$

So, change in y = new value of y- original value of y

$=4x+1-(4x-3)$

$=4x-23-(4x-3)$

$=4x-23-4x+3$

= -20

Thus, the value of y will be decreased by 20 units.
