Question

If Y is 12more than 6times X and X is 4.5 more than one- eighth of Y

Answer 1

this is the value of x and y... where x=18 &y=126

Answer 2

The value of Y is 156 and value of X is 24.

Step-by-step explanation:

We are given the following in the question:

Y is 12 more than 6 times X.

Thus, w can write the equation as:

$Y = 12 + 6X$

X is 4.5 more than one- eighth of Y.

Thus, we can write the equation:

$X = 4.5 + \dfrac{1}{8}Y$

Solving the two equations by substitution method, we get,

$Y = 12 + 6(4.5 + \dfrac{1}{8}Y)\\\\Y =39 + 0.75Y\\\\0.25 Y = 39\\\Rightarrow Y = 156\\\Rightarrow X = 4.5 + \dfrac{156}{8} = 24$

Thus, the value of Y is 156 and value of X is 24.
