Answer:
y = 23
x = -4.5
Step-by-step explanation:
Given:
Equation
8x + y = -13 ......eq1
8x + 2y = 10........eq2
Find:
Solution
Computation:
Eq2 - Eq1
y = 23
From eq1
8x + y = -13
8x + 23 = -13
8x = -36
x = -4.5

When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number:

. in our rational number the denominator is 1, and the numerator is 3
Now, a rational expression is an algebraic expression in a rational for. If we apply the same to your problem. 4 over x-3 means 4 divided by x-3, or in mathematical notation:

. In this case, the numerator is 4, and the denominator is

.
We can conclude that the equivalent rational expression of <span>4 over x - 3 is </span>
