Question

Which system of equations is represented by the matrix below?

[2 -3|8]
[5 0|10]

A. 2y - 3x = 8
5y = 10

B. 3x - 2y = 8
5x = 10

C. 2x - 3y = 8
5x = 10

Answer 1

C

Explanation:

the x,y matrix will have the form of some x coefficient value, some y coefficient value and then the answer. if one of these values are missing you use a 0 as placeholder. look at the coefficients here. you know one equation will have an x coefficient of 2 and a y coefficient of -3 with a solution of 8 and the other equation will have x coefficient of 5 and no y at all with a solution of 10. only option c meets these criteria
