Answer:
x=-2 y=3
Step-by-step explanation:
The substitution is basically given to you. Exchange x from the second equation with y-5
Once that is done and you combine the parentheses you get:
2y-10+y=-1
Add 10 on both sides of the equal sign
You get:
3y=9
Divide both sides by 3
y=3
To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
Answer: 102,400,000,000,000,000,000
First do 20^10 = 10,240,000,000,000.
Then, multiply 10,240,000,000,000 * 10,000,000 to get 102,400,000,000,000,000,000.
