Question

Noah started to solve the equation –4.6p – 6.3p + 3.9 = –9.18 below.​

Answer 1

Answer:

$The~answer~you~should~be~getting~is:\\p = 1.2$

Step 1 : First, we'll have to reorder the terms:

$3.9 + -4.6p + -6.3p = -9.18$

Step 2 : Now combine the like terms:

$=-4.6p + -6.3p = -10.9p\\= 3.9 + -10.9p = -9.18$

Step 3 : Solving:

$3.9 + -10.9p = -9.18$

Step 4 : Solving for variable "p":

$Move~all~the~terms~containing~"p" to~the~left,~all~other$ $terms~to~the~right.$

$Add~"-3.9"~to~each~side~of~the~equation.$

$=3.9 + -3.9 + -10.9p = -9.18 + -3.9$

Step 5 : Now combine the like terms:

$=3.9 + -3.9 = 0.0$

$=0.0 + -10.9p = -9.18 + -3.9$

$=-10.9p = -9.18 + -3.9$

$=-9.18 + -3.9 = -13.08$

$=-10.9p = -13.08$

Step 6 : Then, divide each side by "-10.9":

$p=1.2$

And that's your answer!

$p=1.2$
