Math Questions?

LOL. LAZY. DO YOUR OWN HOMEWORK.

1. (11x - 37) + (5x + 59) = 54

11x - 37 + 5x + 59 = 54

11x + 5x = 54 + 37 - 59

16x = 32

x = 32 / 16

x = 2

2. 3x - 35 = 9x - 59

3x - 9x = -59 + 35

-6x = -24

x = -24 / -6

x = 4

3. 9x - 3 = 8x - 7

9x - 8x = -7 + 3

x = -4

4. (5w + 24) + (2w + 13) = 156

5w + 24 + 2w + 13 = 156

5w + 2w = 156 - 24 - 13

7w = 119

w = 119 / 7

w = 17

5. (3x + 10) - 5x = 6x - 50

3x + 10 - 5x = 6x - 50

3x - 5x - 6x = -50 - 10

-8x = -60

x = -60 / -8

x = 7.5

6. 8y +12 = 2y - 18

8y - 2y = -18 - 12

6y = -30

y = -30 / 6

y = -5

7. 7T - 8T + 4 = 5T - 2

7T - 8T - 5T = -2 - 4

-6T = -6

T = -6 / -6

T = 1

8. 13C + 40 = 9C - 20 + C

13C - 9C - C = -20 - 40

3C = -60

C = -60 / 3

C = -20

9. (6a - 54) - (5a + 27) = 23

6a - 54 - 5a - 27 = 23

6a - 5a = 23 + 54 + 27

a = 104

10. (2 + 4y) - (y + 9) = 26

2 + 4y - y - 9 = 26

4y - y = 26 - 2 + 9

3y = 33

y = 33 / 3

y = 11

11. (12C + 35) - (5C - 11) = -2

12C + 35 - 5C + 11 = -2

12C - 5C = -2 - 35 - 11

7C = -48

C = -6.86

------------------------------------------------------------------------------------

1) Remove parenthesis around.

2) If there are - or + sign at the left of the bracket, expand their bracket. Example :

- (5C - 11)

= -5C + 11

3) Combine like terms and must bring all unknown to the left.

1)(11x-37)+(5x+59)=54

(-407)+(5x+59) =54

(-348+5x) =54

5x =348+54

5x =402

x =80.4

2)3x-35=9x-59

3x-9x =-59+35

-6x =-24

6x =24

x =4

other qns i nt in the mood to do it so do it urself

Lazy...i just do one...

6. 8y+12=2y-18

8y-2y=-18-12

6y=-30

y=-5

I'll contribute one

3) . . . . 9x -3 = 8x - 7

x = - 4
