<span>2x = 3y−1 (1st)

​6x−9y=−3
6x = 9y - 3
divide 3 to both sides
2x = 3y - 1 (2nd)

both equation (1st) and (2nd) is the same
answer
Many infinitely solutions</span>

2x= 3y-1
6x-9y= -3
So we can solve in 2 ways.

1- Substitution
2- Summate 2 equations

The 1st solution:
Choose x or y's congruent in one of the equation and find with residual equation.

2x= 3y-1
6x is three times of 2x so 6x= 3(3y-1)
6x= 9y-3

6x-9y=-3
9y-3-9y= -3
0=0

Solution set = (R)

2nd solution;

2x-3y=-1
6x-9y= -3

Multiple the first equation with (-3).

-6x+9y=3
  6x-9y=-3

0=0
Solution set= (R)

Hope it helps!

Layla wrote a report on insects. She listed the lengths of a tiger beetles, carpenter ants, and aphids. The lengths were 1/2 inc
ahrayia [7]
First we would change the fractions into decimals and compare them. That way it would be easy to solve when needed.

1/2=0.50
5/8=0.625
1/8=0.125
   
Now we can see that 1/8 (0.125) is the smallest, followed by 1/2 (0.50), and 5/8 the largest. Now we can match the sizes with the insects.

Since the tiger beetle is the largest we will place that with the length of 5/8 since that is the largest.

The carpenter ant is second largest so it would be matched with 1/2

The aphid is the smallest so that would be with 1/8 as the smallest

*Hope that helped :D*

What is multiplication
yawa3891 [41]
<h2>Answer:</h2>

A way of adding numbers. Contrast to division.

<h2>Step-by-step explanation:</h2>

Multiplication is when you have a number that you need to multiply by that number. Okay, let me give you an example:

2x4 means = 2+2+2+2 or 4+4

3x6 means = 3+3+3+3+3+3 or 6+6+6

the answer will always be the same.

GOOD LUCK !! :)
