Answer:

sin90° = 1.

Step-by-step explanation:

Rudiy27

Answer:

x=-\frac{28}{3}\\\\y=7

Step-by-step explanation:

Given the system of equations:

\left \{ {{-5+2y=9} \atop {3x+5y=7}} \right.

You can pply Substitution method:

First you must solve for "y" from the first equation:

-5+2y=9\\\\2y=9+5\\\\2y=14\\\\y=\frac{14}{2}\\\\y=7

Therefore, the second and final step to solve the system of equations is to substitute the value of "y" into the second equation and solve for "x":

3x+5(7)=7\\3x=7-35\\\\x=-\frac{28}{3}
