Find the value of x

1. 6x+39x+2 = -(2x+7)+x

2. 1/2[2/3(4x - 1)-(3x - 2) = 5x/9

3. 5x - 1/2 = 4x + 3/4

4. -3[4x + 2(x - 4)] = -5[2(x + 5)]

5. -6x - [4 - (2 - 3x)] = 4(x + 1)

6. 9x/5 + 8 = 7x/4 - 10 + 34

7. -8[4x + 5(-2x - 4)] = -7[3(1/3x + 3)] - 7

8. 2x/3(3 + 9) = 7x/9(27/7 - 9) + 9/8x[2/3(4x - 1)]


answers: 1. x = -13/10
2. x = 3/4
3. x = 5/4
4. x = -74/-8 or 37/4
5. x = -6/13
6. x = 160
7. x = -2
8. x = -20/9

LITERAL EQUATIONS

1. 1/2(3p - t) = t-8 solve for p

2. a + 2b/3c = 4a solve for c

3. x + y = 5 - x/2 solve for x

4. L = a + (n - 1)d solve for n

5. -a = (j - 3a)7 solve for j

6. f = 16/5c + 32 solve for c

7. A = 3/4rb(2/3L + 2/3c) solve for L

8. 3 + a = 1/2bh(8 - 1/2c) solve for c


answers: 1. p = t - 16/3
2. c = 2b/9a
3. x = (10 + 2y)/3
4. n = (L - a + d)/d
5. j = 20a/7
6. c = 5/16f + 10
7. L = (A - 1/2rbc)/ 1/2rb
8. c = -2 + (3+a)/ 1/2bh
