What is the value of x in the equation -6x = 5x+22?
0-22
0-2
O 2
O 22

x = -2

Step-by-step explanation:

-6x = 5x + 22 the first step is to move 5x to the other side of the equal sign, so      subtract 5x from both sides of the equation

-11x = 22 in order to isolate x, divide both sides by -11

x = 22/ -11

x = -2

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
