Simplify (3x – 5) + (5x + 1).

Andrej [43]

Answer:

(-2x - 6)

Step-by-step explanation:

The given expression is ( 3x - 5 ) - ( 5x + 1 )

We have to simplify the given expression

First we will open the bracket having negative notation outside.

( 3x - 5 ) - 5x - 1

3x - 5 - 5x - 1

Now we will collect the similar terms together.

3x - 5x - 5 -1

-2x - 6

So the simplified form of the expression is (-2x - 6)

Eight times a number increased by 9 exceeds 7 times the number by 15. Find the number.

Alborosie

Turn it into math terms bit by bit. let x be "a number"

8 times a number is 8×x

increased by 9 is +9

7 times a number is 7×x

exceeds is minus

by 15 is =15

now we put it together.

$8 \times x + 9 - 7 \times x = 15$
solve
$8x + 9 - 7x = 15 \\ x + 9 = 15 \\ x = 6$
