Question

Please solve!!!!thanks

Answer 1

Answer:

h = 11. 5.

Step-by-step explanation:

(4h - (21 - 8h)/3 = (15 + 6(h - 1)/2

Cross multiplying, we get:

2(4h - (21 - 8h) = 3(15 + 6(h - 1)

8h - 2(21 - 8h) = 45 + 18(h - 1)

8h - 42 + 16h = 45 + 18h - 18

8h + 16h - 18h = 45 - 18 + 42

6h = 69

h = 11. 5

Answer 2

Answer:

11.5

Step-by-step explanation:

$\frac{4h-(21-8h)}{3} = \frac{15 + 6(h - 1)}{2} \\ \frac{4h - 21 + 8h}{3} = \frac{15 + 6h - 6}{2} \\ 3(15 + 6h - 6) = 2(4h - 21 + 8h) \\ 45 + 18h - 18 = 8h - 42 + 16h \\ 27 + 18h = 24h - 42 \\ 18h - 24h = - 42 - 27 \\ - 6h = - 69 \\ h = \frac{ - 69}{ - 6} \\ cancel \: the \: minus \: signs \\ h= 11.5$

HOPE IT HELPS

HAVE A NICE DAY :)
