Answer:
5 : 1 or 10 : 2
Step-by-step explanation:
The given expression is 2x-3 .
So when x =1, we will get 2(1)-3 = 2-3 =-1
When x=2, we will get, 2(2) -3 = 4-3 =1
When x=3, we will get 2(3)-3 = 6-3=3
When x=4, we will get 2(4)-3 = 8-3=5
So the required result of the expansion is -1+1+3+5=8
Correct option is the second option .
Answer:when x is isolated in the first equation or when a equation is solved for the variable.
