Sagot :
Answer:
infinite number of solutions
Step-by-step explanation:
we can use the substitution method because the second equation is already solved for 'y'
we can substitute 'x-4' for the 'y' in the first equation to get:
x - (x-4) = 4
x-x+4 = 4
x-x = 0
what 'x-x=0' indicates is that there are an infinite number of values that would be solutions
Check:
if we solve the first equation for 'y' we get:
-y = -x + 4
divide all terms by -1 to get:
y = x - 4 which matches the other equation which means this two equations are equal and will create only one line
