Solve the system using elimination.

5x + 8y = –29
7x – 2y = –67

Answers

Answer 1

Answer: 7x-2y+-67
multiply both sides of the bottom by 4 and add 5x+8y=-29
28x-8y=268

33x=-297
x=-9

5(-9) +8y= -29
-45 +8y =-29
8y= 16
y=2

Mags is 2 years older than vector . if mags is 34 years old how old is vector

Answers

Answer:

Vector is 32 years old.

Step-by-step explanation:

As it is given that Mags is 34 years old and he is 2 years older than Vector.

Since Mags is 2 years older than Vector, Vector's age is 2 year less than Mags.

therefore we subtract 2 years from the age of Mags.

= 34 - 2 = 32 years

So Vector is 32 years old.

Answer: it is

Step-by-step explanation:

What is the simplified form of the equation fraction 4 over 5 n minus fraction 3 over 5 equals fraction 1 over 5 n?n = 1
n = −3
n = fraction 3 over 4
n = fraction 1 over 4

Answers

Simple...

so you have...

$(4)/(5) n- (3)/(5) = (1)/(5) n$

You want to isolate the variable,n,....

so subtract....

$(4)/(5) n- (3)/(5) = (1)/(5) n$
$- (4)/(5)n$ $-(4)/(5) n$

Leaving you with.....

$-(3)/(5) = -(3)/(5) n$

Now, divide....

$(- (3)/(5) )/( -(3)/(5) ) = (- (3)/(5)n )/( -(3)/(5) )$

Making n=1

Thus, your answer.

Answer:

n = 1
