Given:
2y - 4 = 0
x + 2y = 5
Solve for x.
Solution:
In order to solve for x, we substitute the value of y of the 1st equation to the second equation.
2y - 4 = 0
2y = 4
2y/2 = 4/2
y =2
Since we have the value of y as 2, we substitute 2 to the second equation
x + 2(2)=5
x + 4 = 5
x = 5 -4
x = 1
Final answer:
x =1
