What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

System of equations are,

y = -5x + 30  .. (i)

x = 10

Now, We can find the solution as;

Plug x = 10 in equation (i);

y = - 5x + 30

y = - 5 × 10 + 30

y = - 50 + 30

y = - 20

Thus, The value of the solution to the system of equations are, (10, - 20)

The correct answer is (10,-20), because the equation already gives you the correct x value. Then, from there you just plug 10 in for x in the y equation. Giving you a -20, :)
