Answer:
equalize the both sides of the functions
Step-by-step explanation:
4x-5 = 2x-5
4x = 2x
2x = x
2 = 1 meaning phi
there is no answer for this problem
Answer:
x = 0, y = -5
Step-by-step explanation:
you're given two equations:
y = 4x - 5
y = 2x - 5
to solve, just substitute y in the second equation.
y = 2x - 5
4x - 5 = 2x - 5
now that you have this, solve for x.
4x - 5 = 2x - 5
subtract 2x from both sides
4x - 5 - 2x = 2x - 5 - 2x
2x - 5 = -5
add 5 to both sides
2x - 5 + 5 = - 5 + 5
2x = 0
divide both sides by 2
2x/2 = 0/2
x = 0
now that you know x, substitute x for 0 in the second equation.
y = 2x - 5
y = 2 * 0 - 5
y = 0 - 5
y = - 5
