Isolate x
subtract 7/8 from both sides
x=4-7/8
4=1+3
x=3+1-7/8
1=8/8
x=3+8/8-7/8
x=3+1/8
x= 3 and 1/8 or 25/8
Answer:
x = 12
Step-by-step explanation:
Given
p(x) = x - 3
To find the zero let p(x) = 0, that is
x - 3 = 0 ( add 3 to both sides )
x = 3 ( multiply both sides by 4 )
x = 12 ← zero of p(x)
Make all the number negative like this:
-2 - 3 - 5 - 4
-2 -3 = - 5
-5 - 5 = -10
-10 - 4 = -14
