Question
What is the y value in the equation x + y = 1?
- y = 1 - x
- y = x – 1
- y = -1 – x
- Both a and c
Hint:
try to solve equation for y .
send each part on lhs to rhs except y .
The correct answer is: y = 1 - x
Given
x + y = 1
step 1 :
send x to rhs so it becomes -x
y = 1- x
so , value of y is 1 - x , choice 1 .
