h = 5n

h - n = 48

solve the system using substitution

three less than twice a number x is equal to 5 more than x. find the number????

2x - 3 = 5 + x

solve for x

(-2^-3x^-7)(2^5 x^6 y^9)=

property of exponents ... $\displaystyle \textcolor{red}{b^c \cdot b^d = b^{c+d}}$

calculate:: x^7y^6z^-5///// x^-4 y^8 z^-8

if this is supposed to be division ... $\displaystyle \textcolor{red}{\frac{b^c}{b^d} = b^{c-d}}$

2(x^2 y)^0 +(3x^2)^0

hint ... $\displaystyle \textcolor{red}{a^0 = 1}$
