Multiply the first equation by -4, to set up the x-coefficients to cancel. Take the value for y and substitute it back into either one of the original equations. Solution: In this example, we will multiply the first row by -3 and the second row by 2; then we will add down as before.

Enter an equation in point-slope form for the line. Slope is O and (6, 7) is on the line.

Crank

Answer:

$\displaystyle y = 7$
