Answer:

1. 2x+2-(2x-14)=5x+2

0x+16=5x+2

16=5x+2

14=5x

14/5=x or 2.8=x

2. 2x+10-(-2x+7)=-7x+14

4x+3=-7x+14

11x+3=14

11x=11

x=1

1) x=2.8

2) x=1

Step-By-Step:

Q1) 2x + 2 - (2x - 14) = 5x + 2

Simply the expression

2x+2-2x+14=5x+2

collect like terms

(2x-2x) + (2+14) = 5x+2

simplify

16= 5x+2

swap sides

5x+2=16

-2 -2

5x=16-2

5x=14

to get x on its own we divide each side by 5 so

5x=14

÷5 ÷5

x= 2.8

Q2) 2x + 10 - (-2x + 7) = -7x + 14

Simply the expression

2x+10+2x-7= -7+14

collect like terms

(2x+2x)+(10-7)= -7+14

simplify

4x+3=7

-3 -3

4x+3-3=7-3

simplify

4x=7-3

4x=4

to get x on its own divide each side by 4 so...

4x=4

÷4 ÷4

x=1

Hope this helped- have a good day bro cya)

Which statement about the solution of the inequality k<-3 1/4 is true?

Juliette [100K]

Answer: Last option

The number -8.4 is a solution to the inequality because -8.4 is located to the left of $-3\frac{1}{4}$ on the number line.

Step-by-step explanation:

Note that: $-3\frac{1}{4} =-3-\frac{1}{4} =-3.25$

The inequality is:

$k$

The inequality is:

This means that the inequality includes all values of the number line that are less than -3.25 or that are to the left of -3.25

__-8.4_________-3.25_-3____0___0.9____________7.1__

Note that the number -8.4 is less than -3.25, because it is to its left on the number line.

Then the correct statement is:

The number -8.4 is a solution to the inequality because -8.4 is located to the left of $-3\frac{1}{4}$ on the number line.
