Given the equation:
y = 2x - 1
y = -x + 5
Solve for the systems of equation.
Solution:
In order to determine the answer, we must first solve for x, by equating or substituting the value of y from the second equation tot the value of y for the 1st equation.
2x - 1 = -x + 5
Transpose -x and -1 to the opposite sides of the equation, hence it must be taken to note that in transposing a number, the sign changes.
2x - 1 = -x + 5
2x + 1 = 5 + 1
3x = 6
Divide both sides by 3 in order to determine the value of x.
3x/3 = 6/3
x = 2
Final answer:
x = 2
