Answer:
(x, y) = (-5, 18)
Step-by-step explanation:
You have done the first two steps.
<h3>3.</h3>7x +2(3 -3x) = 1 . . . . . equation with y substituted
7x +6 -6x = 1 . . . . . . . eliminate parentheses using the distributive property
x = -5 . . . . . . . . . . . . . subtract 6 from both sides, collect terms
<h3>4.</h3>y = 3 -3(-5) . . . . . . . . use the substitution equation to find y
y = 18
The solution is (x, y) = (-5, 18).
Answer:
Option B.
Step-by-step explanation:
Integer: A non fractional complete number is known as integer. It can be either positive or negative or zero.
For examples : ...,-3,-2,-1,0,1,2,3,...
It is a clear that the difference between two consecutive integers is 1. It means we have to add 1 in the integer to get the next integer.
We need to express "next integer after the integer n" mathematically. So, we need to add 1 in n.
Required expression
Hence, the next integer after the integer n is n+1.
Therefore, the correct option is B.
