To find the intersection point, we can substitute the value of 'y' from the second equation into the first equation.
y = -x + 5
Substituting this value into the first equation:
2x + (-x + 5) = 15
Simplifying the equation:
2x - x + 5 = 15
x + 5 = 15
x = 15 - 5
x = 10
Now, substitute this value of 'x' into the second equation to find 'y':
y = -x + 5
y = -(10) + 5
y = -10 + 5
y = -5
Therefore, the intersection point is (10, -5).
Find the coordinates of the intersection point that solves the system of these two linear equations in two variables: 2x+y=15 and y=−x+5.
