Question

What is the value of X in the equation 8X - 2y=48,when y=4

Answer 1

Answer:

x = 7.

Step-by-step explanation:

The given equation is  

$8x-2y=48$

We need to find the value of x, when y=4.

Substitute y=4 in the given equation and then solve for x.

$8x-2(4)=48$

$8x-8=48$

Add 8 on both sides.

$8x=48+8$

$8x=56$

Divide both sides by 8.

$x=\dfrac{56}{8}$

$x=7$

Therefore, the value of x is 7, when y=4.

Answer 2

Answer:

X=7

Step-by-step explanation:

8x-2y=48

8x-2(4)=48

8x-8=48

8(7)-8=48

56-8=48
