Answer:

1.

-2 = x/4 + 1

Subtract 1 from both sides:

-2 - 1 = x/4 + 1 - 1

-3 = x/4

Multiply both sides by 4:

-3 * 4 = x/4 * 4

-12 = x

2.

3x+5

3.

X= 12 or 18

This could be read two different ways.

0=2/3x-12

12=2/3x

12÷2/3=x

12*3/2=x

18=x

—-OR—-

0=2/3(x-12)

0=2/3x-8

8=2/3x

8÷2/3=x

8*3/2=x

12=x

The product of eight and a number decreased by four is the same as eight plus five time the same number.
dedylja [7]

Answer:

The Answer is: The Number is 4

Step-by-step explanation:

Let n = the number.

Eight times a number minus 4 equals 8 plus 5 times the number.

8n - 4 = 8 + 5n

3n = 12

n = 4, the number is 4.

Proof:

8(4) - 4 = 8 + 5(4)

32 - 4 = 8 + 20

28 = 28

Hope this helps! Have an Awesome Day!! :-)

5 1/3 x+8 1/2 =3 1/3 please answer need answers ASAP
SVETLANKA909090 [29]

Answer:

5 1/3 x+8 1/2 =3 1/3 ?

the correct answer is -1.774

Step-by-step explanation:

51/3x + 81/2=31/3 In order to find x, we follow BODMAS rule

so we have,[ 51/3] x + 81/2 =31/3

we have   51x/3 + 81/2=31/3

we collect the like terms;

51x/3= 31/3- 81/2

finding the lcm

51x/3= 2[31} - 3{81}/6

51x/3= 62-243/6

51x/3= -181\6

by using cross multiplication

we have;

6{51x}= 3{-181}

306x = -543

divide both sides by 306

we have;

x = - 1.774

check your answer from

306x=-543

306{-1.774}= -543

-543= -543
