4x+18=7x-12

We move all terms to the left:

4x+18-(7x-12)=0

We get rid of parentheses

4x-7x+12+18=0

We add all the numbers together, and all the variables

-3x+30=0

We move all terms containing x to the left, all other terms to the right

-3x=-30

x=-30/-3

x=+10

Hope this helps :)

How to solve using Substitution or Elimination?<br> y=3x-1<br><br> y=2x+2

n200080 [17]

By elimination:

y = 3x - 1

y = 2x + 2

Subtract the second equation from the first

0 = x - 1

y = 2x + 2

Subtract the first equation from the second

0 = x - 1

y = x + 3

Subtract the first equation from the second again

0 = x - 1

y = 4

Subtract x from both sides of the first equation

- x = - 1

y = 4

Divide the first equation by (-1)

x = 1

y = 4

<h3>So, the solution is x = 1 and y = 4 {or: (1, 4)}</h3>

Cereal costs 2.79 for 16.4 ounces. At this rate how much does 25 ounces of cereal cost? Round to the Nearest Cent.

ankoles [38]

Answer:

$4.25

Step-by-step explanation:

We can create a proportion to find how much 25 oz will cost:

$\frac{2.79}{16.4}$ = $\frac{x}{25}$

We can cross multiply to find x.

16.4x = 69.75

x = 4.25

So, this means 25 ounces of cereal will be $4.25
