Solve this by substitution
frozen [14]

Answer:

y= 1 and x=-2

Step-by-step explanation:

Since they both equal y, you can equal them to each other:

x + 3 = 2x + 5

Then solve:

x - x + 3 = 2x - x + 5

3 - 5 = x + 5 - 5

-2 = x

Substitute x in either equation to solve for y:

y = (-2) +3

y = 1

Or the other equation:

y = 2(-2) + 5

y = -4 + 5

y = 1

hope this helps :)

A local concert promoter purchases 2 3/4 pages of ads. When one of the concerts is cancelled, the promoter cancels 1 5/8 pages o
Lynna [10]

Answer:

1\frac{1}{8} pages

Step-by-step explanation:

Since the concert promoter started with 2 \frac{3}{4} pages of ads but had to cancel 1 \frac{5}{8}, subtracting the cancelled amount from the original amount will give the amount of advertising space the promoter is now actually using:

 2 \frac{3}{4}  = 2 \frac{6}{8}

- <u>1 \frac{5}{8}</u>      - <u>1 \frac{5}{8}</u>

     1\frac{1}{8} pages

In order to subtract fractions, you need to have like denominators, so you need to convert \frac{3}{4} into an equivalent fraction with a denominator of '8'.  Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.
