Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
The most that you can do is:
13p = 31-7k so that p = (31-7k)/13
7p plus 6p equals 13p. You simply combine the like terms by adding the coefficients (7 and 6) together. Therefore, the equation simplifies to 13p.
P2 + 13p - 30 = 0 Answer: p= -15, p = 2
p=10
The solution isp = +2 or p = -15 .Here is how to get it.p2 + 13p - 30 = (p - 2) ((p + 15)So, if p2 + 13p - 30 = 0 then (p - 2) ((p + 15) = 0.The product of two numbers equals 0 if and only one of the factors is zero.so solve the linear equations:p -2 = 0 and p + 15 = 0 and getp = +2 or p = -15 .

-31=8-6p-7p -31=8-13p ==add the -6p and the - 7p together -39=13p =======move the 8 over to the other side p=3 =======divide both sides by 13 to get p by itself
p = -12
16p + 6q - 3p - 8q = (16p - 3p) + (6q - 8q) = 13p -2q
13p/13p = Cacek diwb by 'p' HYence 13/13 = Cancel down by '13' Hence =1. The answer !!!!
It is 13p/1
1
This can be simplified to -10p = -150 p = -150/-10 p = 15
