Answer:
1) x + 4 = 11
Subtract 4 on both sides, to get x = 7 .
2) x + 3 = 24
Subtract 3 on both sides, to get x = 21 .
3) 4x = 12
Divide 4 on both sides, to get x = 3 .
4) 5x + 3 = 33
First subtract 3 on both sides to get
5x = 30, now divide 5 on both sides, to
get x = 6 .
5) 8x + 5 = 3x + 20
First subtract 5 from 20 in order to
move it, now you have 8x = 3x + 15 .
Next subtract 3x from 8x in order to
move it, now you have 5x = 15 . Lastly
divide 5 on both sides, to get x = 3 .
1) 1/2 x = 4
Multiply both sides by 2, to get 1x = 8,
or x = 8 .
2) 4/3 x = 4
Multiply both sides by 3, to get 4x = 12 .
Next divide 4 on both sides to get
x = 3 .
3) 2x + (-4) = 8
Add 4 on both sides, to get 2x = 12 .
Next divide 2 on both sides to get
x = 6 .
4) 1/3 x + 1/2 x = 20
First multiply the denominators to get a
common denominator of 6 and then
add 3 and 2, to get the numerator. Now
you have 5/6 x = 20 . Next multiply 6
on both sides to get 5x = 120 . Lastly
divide 5 on both sides to get x = 24 .
5) 1/3 x = 1/5 x + 10
First multiply the denominator to get a
common denominator of 15 and then
subtract 3 from 5 to get the numerator.
Now you have 2/15 x = 10 . Next
multiply 15 on both sides to get
2x = 150. Lastly divide 2 on both sides
to get x = 75 .
Hope this helped :)
Btw sorry it's so long.
