Multiply the first equation by -666 and the second by 45:-
-29970x + 217116y = -63936
29970x - 34965y = 18900
adding these 2 equations:-
182151y = -45036
y = -0.24724
x = 96 + 326* -0.24724 / 45 = 0.3422
x = 0.342, y = -0.247 Answer (correct to the nearest thousandth)
Point slope is

the slope is 7 and the coordinates given are (5,3), you plug in that into the equation and end up with
"Half of a number decreased by 27" can be displayed as:
<u>1/2x - 27</u>
