Write as a Vector Equality 2a+b=7 , 3a+1.5=21

Problem

{[2*a+b=7],[3*a+1.5*b=21])

Solution

1. Identify the variables and coefficients in the system of linear equations.

2. Group the coefficients of the variable a into one vector and the coefficients of the variable b into another vector.

3. Represent the constants on the right side of the equations as a single resultant vector.

4. Construct the vector equality by multiplying each variable by its corresponding coefficient vector and setting their sum equal to the constant vector.

Final Answer

a*[[2],[3]]+b*[[1],[1.5]]=[[7],[21]]
