Ο Α.
4x + 5y = 3
- 4x - 5y = 2
ОВ.
12x + 15y = 9
- 12x + 18y = 6
O C.
4x + 5y = 3
- 4x - 3y = 1
OD.
12x + 15y = 9
- 12x - 18y = -6

D

Step-by-step explanation:

I took the test

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

just keep timing it by 4.
