5x - 4y = 42 ------ (1)
x - 6y = 24 ----------(2), multiply eq. 2 by 5 we get
5x - 30y = 120 -----(3),
now use eq. (3) - (1),
5x - 30y = 120
-(5x - 4y = 42)
- 30y + 4y = 120 - 42,
-26y = 78, y = -78/26 = -3,
x = 24 + 6y = 24 + (6*[-3]) = 24 - 18 = 6,
x = 6, y = -3.

Step-by-step explanation:
A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial, Outer means multiply the outermost terms in the product, Inner means multiply the innermost terms, and Last means multiply the terms which occur last in each binomial.
An algebraic expression consisting of one or more summed terms, each term consisting of a constant multiplier and one or more variables raised to integral powers.
The answer to Number 9 is D and the answer to number 10 is D because in number 9, City P is above 0 and City R is a negative number and below 0. In number 10, Point A is at -20 and Point B is 5 less. That would get you the equation -20-5. -20-5 = -25. On a number line, -25 is less than -20 and would be on the left side of Point A. Hope this helps!
180-65 = 115
6x + 7 = 115
6x= 108
x= 108/6
x=18
