Write as a Vector Equality 2x-5=20 , y=x-7

Problem

2*x−5=20,y=x−7

Solution

1. Solve the first equation for x to find the specific value of the first variable.

2*x=25

x=12.5

2. Substitute the value of x into the second equation to find the value of y

y=12.5−7

y=5.5

3. Construct the vector equality by placing the variables in a column vector on the left and their corresponding values in a column vector on the right.

[[x],[y]]=[[12.5],[5.5]]

Final Answer

[[x],[y]]=[[12.5],[5.5]]
