Answer:
x=1 and x=-1/3
Step-by-step explanation:
By the zero product property, we have two separate equations, x-1=0 and 3x+1=0
x-1=0
x=1
3x+1=0
3x=-1
x=-1/3
So x=1 and x=-1/3
Hope this helped!
Answer:
-37
Step-by-step explanation:
for the first equation to equal 4 the x must equal -6.
because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.
So now plug -6 into the new problem so now it is
5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!
hope this helps :)
