Answer:
The value of x for the given expression is 
Step-by-step explanation:
Given as :
<u>The expression is written </u>
3
- 1
× x = 1
Or, 1 × x = 3 - 1
Or, 
× x = 
- 1
Or, 
× x = 
- 1
Or, × x = 
Or, × x = 
∴ x = 
Or, x = 
I.e x =
So, The value of x =
Hence The value of x for the given expression is Answer

y-8+3y+12
4y+4 is your answer
Answers:
k = 13The smallest zero or root is x = -10
===============================
Work Shown:
note: you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
