1. Solve the equations below.
Sergio039 [100]

Step-by-step explanation:

A) 3x + 8 = 23

3x = 23 - 8

3x = 15

x = 15 / 3 = 5

B) 5x + 1 = 3x + 17

5x - 3x = 17 - 1

2x = 16

x = 16 /2 = 8

C) 4 (x+2) = 32

4x + 8 = 32

4x = 32 - 8

4x = 24

x = 24 / 4 = 6

Someone please help me on number 3 and if the others are wrong please let me know ITS MULTI STEP EQUATION COMBINING LIKE TERMS
weeeeeb [17]

Answer:

#1: x = 3; #2 c = 1/2; #3 = x = 22; #4 is correct (x = -8)

Step-by-step explanation:

for the first equation everything was right until 22x = 66

after

22x = 66

you must divide everything by 22

x = 3

that is for #1

for the second equation you copied down the question wrong

the negative is still there

6c - 8 - 2c = -6

combine 6c and -2c

4c - 8 = -6

the negative remains on the 8

add 8 to both sides

4c = 2

divide 4 to both sides

c = 2/4 or just 1/2

for the third equation you must first combine like terms

-3x + 25 + x + 21 = 2

combine -3x and x & 25 and 21

-3x + x = -2x

25 + 21 = 46

-2x + 46 = 2

then subtract 46 from both sides

-2x = -44

now divide both sides by -2

x = 22

that is your answer

number four should be correct
