Answer:
- 1
- - 9
- 13
- 15
Step-by-step explanation
- 7(6x-1)+x=36
- => 42x - 7 + x = 36
- => 43x - 7 = 36
- => 43x = 36 + 6 = 43
- => x = 43 / 43 = 1
- 11-2(8+3p)=7²
- => 11 - 16 - 6p = 7^2
- => 11 - 16 - 6p = 49
- => -5 - 6p = 49
- => -6p = 49 + 5 = 54
- => p = (54) / (-6) = - 9
- 1/4(5b+11)=19
- => (5/4)b + (11/4) = 19
- => (5/4)b = 19 - (11/4) = 65 /4
- => b = (65/4) / (5/4) => (65/4) * (4/5) = 13
- 2/7(4m-18)=12
- => (8/7)m - (36/7) = 12
- => (8/7)m = 12 + (36/7) = 120/7
- => m = (120/7) / (8/7) = 120 /8 = 15
