a sequence is a function whose domain is the set of natural numbers.
natural numbers are all the negative and positive integers
I used my calculator and got x=1 y=3
solve for y to put them in your calculator
2.1x+4.2y=14.7
y = (14.7 -2.1x)/4.2
−5.7x−1.9y=−11.4
y=(-11.4 +5.7x)/(-1.9)
then using the ploting tool I plotted them and found where they intersected
Answer:
x=3
Step-by-step explanation:
8x-28-2x=-10
We move all terms to the left:
8x-28-2x-(-10)=0
We add all the numbers together, and all the variables
6x-18=0
We move all terms containing x to the left, all other terms to the right
6x=18
x=18/6
x=3
