Answer:
J=-50
Step-by-step explanation:
X= -4; f(x)= -15
X= 2; f(x)= 3
X=5; f(x)= 12
In the problem, the first equation should be represented like this base on the variable given in the problem:
20p + 9t = 44.4
with that equation, the second equation would is given by this formula, in response with the additional number of paperback and textbook
21p + 14t = 51
to get the system equation in getting the mass of each variable, you should subtract the two equation to simplified the formula.
20p + 9t = 44.4
- 21p + 14t = 51
-------------------------
p + 5t = 6.6 // this is the system equation that could be use in getting the mass of each object
x = 3
Step-by-step explanation:
5x = 3x + 6
5x - 3x = 6
2x = 6
x = 6/2
x = 3
