1 in scientific notation it saves time and 2 its professional,and looks cleaner
Y=-3/2 + ?
21/2=-3/2 + ?
-?= -3/2-21/2
-?= -24/2
-?=-12
?=12
The equation is y=-3/2x + 12
If you cross multiply so you times the denominators together to get 15 and then times 4 by 3 and 2 by 5 to get the numerators so the question would be: 12/15-10/15 = 2/15
X + y = 51
x - y =15
2x = 66
x = 33
33 + y = 51
y = 18
