Question

8x + y = 16. How do you get to the answer (6, 32)?

A) Substitute x = 6 and y = 32 into the equation.
B) Solve for x and y separately.
C) Use graphing software to find the solution.
D) Perform matrix operations to find the solution.

Answer 1

The easiest and most straightforward way to find the solution to the equation 8x + y = 16 is to substitute x = 6 and y = 32 into the equation:

Substituting x = 6:

8(6) + y = 16

48 + y = 16

Solving for y:

y = 16 - 48

y = -32

Therefore, the answer is (6, -32).
