Question

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

Answer 1

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
