Answers

Answer 1
Answer: Hello,
y=x+2==>x-y=-2 (1)
6x-4y=-10==>3x-2y=-5 (2)

-2*(1)+(2)==>x=4-5==>x=-1
(1)==>y=-1+2=1

How to solve a equation.

Based on the information given, we are informed that Tom starts to read a book with 490 pages today. Sundays he reads 25 pages and on all other days he reads 4 pages.

Let the number of days be represented by x. Therefore, the equation to solve the question will be:

25 + (4 × x) = 490

25 + 4x = 490

4x = 490 - 25

4x = 465

x = 465/4

x = 116.25

x = 117

Therefore, he'll use 117 days to read the book.
