solve the following system of equations using substitution x+y+z=7y=32x+y-z=5enter your answer in the form of (x,y,z)

murzikaleks [220]

Given equations:

$x+y+z=7\ldots(1)$ $y=3\ldots(2)$ $2x+y-z=5\ldots(3)$

Substitute 3 for y in equation (1);

$\begin{gathered} x+3+z=7 \\ x+z=7-3 \\ x+z=4\ldots(4) \end{gathered}$

Substitute 3 for y in equation (3);

$\begin{gathered} 2x+3-z=5 \\ 2x-z=5-3 \\ 2x-z=2\ldots(5) \end{gathered}$

Adding equation (4) and (5);

$\begin{gathered} (x+z)+(2x-z)=4+2 \\ x+z+2x-z=6 \\ 3x=6 \\ x=\frac{6}{3} \\ x=2 \end{gathered}$

Substitute 2 for x in equation (4);

$\begin{gathered} 2+z=4 \\ z=4-2 \\ z=2 \end{gathered}$

Therefore, the values of (x,y,z) is (2,3,2).

AlladinOne [14]

Answer:

We know that the force pulling the box in the positive x direction has a magnitude of m g sin 30 . Using Newtons Second Law, F = ma , we just need to solve for a :

ma=mgsin30

a=gsin30

=(10m/s2)(0.500)

=5m/s2
