8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
7x + 5y 7(3) + 5(2) 21 + 10 = 31
x=0 y=2
2x - 5y = -10 So 5y = 2x + 10 and therefore y = (2/5)*x plus something So the slope is 2/5 or 0.4
8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4
The Commutative Property of Addition.
No.

2y+5y=10 7y=10 y=10/7
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
y=-39
9y+3=5y+13 4y=10 y=10/4 or 5/2 or 2.5

x + 5y = 10 5y = -x + 10 y = -x/5 + 2 m = -1/5 or .2
