Question

Which shows the correct first step to solving the system of equations in the most efficient manner? 3 x 2 y = 17. X 4 y = 19. X = negative 4 y 19 x = StartFraction negative 2 y 17 Over 3 EndFraction 4 y = negative x 19 y = StartFraction negative 3 x 17 Over 2 EndFraction.

Answer 1

The correct first step to solving the system of equations in the most efficient manner is x = -4y +19.

The given system of equations is;

$\rm 3 x + 2 y = 17\\\\x + 4 y = 19$

What is the first step to solving an equation?

The first step would be to rearrange the variables in the second equation so we have a defined expression for x.

We would want to do this so we could then plug in the defined expression for x into the other equation and solve for the other variable.

x + 4y = 19

Rearrange this by getting the 4y to the other side.

We can get 4y on the other side by subtracting 4y from both sides

x + 4y - 4y = 19 - 4y

x = -4y + 19

Hence, the correct first step to solving the system of equations in the most efficient manner is x = -4y +19.
