2 [-3x+2y=8]
6x-2y=-20
-6x + 4y = 16
6x - 2y = -20
2y = -4
y = -2
use the first eq (u can use any) then substitute the value of y
-3x + 2(-2) = 8
-3x -4 = 8
-3x = 12
x = -4

Answer:
7/8 > 2/5
Step-by-step explanation:
7/8 is greater than 2/5.
Consecutive integers are integers that follow one another. For example, 2,3,4,5,etc.... are consecutive integers
So algebraically, consecutive integers follow the form x, x+1, x+2, etc...
Since the sum of two consecutive integers is 239, this means:
x%2Bx%2B1=239
2x%2B1=239 Combine like terms on the left side
2x=239-1Subtract 1 from both sides
2x=238 Combine like terms on the right side
x=%28238%29%2F%282%29 Divide both sides by 2 to isolate x
x=119 Divide
So our first number is x=119
So to find the next number, simply add 1 to it to get 119%2B1=120
Answer: So our two page numbers are 119 and 120
