Answer 1

Answer:

1. 1
2. - 9
3. 13
4. 15

Step-by-step explanation

- 7(6x-1)+x=36

1. => 42x - 7 + x = 36
2. => 43x - 7 = 36
3. => 43x =  36 + 6 = 43
4. => x = 43 / 43 = 1

- 11-2(8+3p)=7²

1. => 11 - 16 - 6p = 7^2
2. => 11 - 16 - 6p = 49
3. => -5 - 6p = 49
4. => -6p = 49 + 5 = 54
5. => p = (54) / (-6) = - 9

-  1/4(5b+11)=19

1. => (5/4)b +  (11/4) = 19
2. => (5/4)b = 19 - (11/4) = 65 /4
3. => b = (65/4) / (5/4) => (65/4) * (4/5) = 13

- 2/7(4m-18)=12

1. => (8/7)m - (36/7) = 12
2. => (8/7)m = 12 + (36/7) = 120/7
3. => m = (120/7) / (8/7) = 120 /8 = 15
