Question

solve equation
4(3p+9)-5(6p-3)=3(p-7)-6(7p_5)
​

Answer 1

Step-by-step explanation:

$12p + 36 - 30p + 15 = 3p - 21 - 42p + 30$

$12p - 30p - 3p + 42p = - 21 + 30 - 36 - 15$

$- 18p - 3p + 42p = 9 - 36 - 15$

$- 21p + 42p = - 27 - 15$

$21p = - 42$

$p = \frac{ - 42}{21}$

Divide it by 3.

$p = \frac{14}{7}$

$2$

Answer 2

Question

4(3p + 9) - 5(6p - 3)= 3(p - 7) - 6(7p - 5)

To find:

Value of p

Step-by-step explanation:

• 4(3p + 9) - 5(6p - 3)= 3(p - 7) - 6(7p - 5)
• 12p + 36 - (30p - 15) = 3p - 21 - (42p - 30)
• 12p +36 - 30p + 15 = 3p - 21 - 42p +30
• -18p + 36 + 15 = -39p + 9
• -18p + 51 = -39p + 9
• -18p + 39p = 9 - 51
• 21p = -42
• p = $\frac{-42}{21}$
• p = -2

So the value of p is -2
