Question

Y = 2x
6x - 2y = 8

Answer 1

x = 4 and y = 8

Explanation:

It is a simultaneous equation

y = 2x --- (1)

6x - 2y = 8 ---(2)

Using substitution method:

Substitute equ1 into equ2:

6x - 2(2x) = 8

6x - 4x = 8

2x = 8

x = 8/2

x = 4

From equ1: y = 2x, substituting back the value of x, we have:

y = 2(4)

y = 8

Answer 2

X= 4
Ý= 8

Step 1: You would need to plug in what Y equals. 6x-2(2x)=8

Step 2: you would then distribute the -2 in the parentheses 6x-4x=8

Step 3: you would subtract 6x to 4x since they have the same variable 2x=8

Step 4: divide 2 to figure what x; when you’re done just plug in your x into the equation again to figure out y.
