Answer:
4.9
Step-by-step explanation:
[tex]2.5 + 3(5 - 2.1p) = - 13.37[/tex]
1) Open the brackets by multiplying 3 with each term present inside the bracket.
[tex] = > 2.5 + 15 - 6.3p = - 13.37[/tex]
2) Add the constant teems present in left-hand side.
[tex] = > 17.5 - 6.3p = - 13.37[/tex]
3) Take 17.5 to right-hand side by changing its sign from positive to negative.
[tex] = > - 6.3p = - 13.37 - 17.5[/tex]
[tex] = > - 6.3p = - 30.87[/tex]
4) Take -6.3 to right-hand side by dividing -30.87 by --6.3.
[tex] = > p = \frac{ - 30.87}{ - 6.3} = 4.9[/tex]
