Question

Find the answer for "X"

Answer 1

(x, y) = (2, 5)

Explanation:

You want to solve the system of equations ...

• y = 2x +1
• x = 12 -2y

Solution

Substituting for y, we have ...

x = 12 -2(2x +1)

x = 12 -4x -2 . . . . . eliminate parentheses

5x = 10 . . . . . . add 4x

x = 2 . . . . . . divide by 5

Then the value of y is ...

y = 2(2) +1 = 5

The solution is ...

• x = 2
• y = 5
