Answer:
(-1,-1)
Step-by-step explanation:
 finding y
    -6x + 5y = 1
  + (6x + 4y = -10)
---------------------------
               9y = -9
                 y = -1
finding x
-6x + 5(-1) = 1
-6x - 5 = 1
     + 5 = +5
-6x = 6
x= -1
 
        
             
        
        
        
<em><u>Answer: x=-2 *The answer should be the negative sign.*</u></em>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
remove parenthesis
-15x-15*4=-30
15*4=60
-15x-60=-30
add 60 both sides of an equation.
-15x-60+60=-30+60
simplify.
-15x=30
divide by -15 both sides of an equation.
-15x/-15=30/-15
simplify.
30/15=2
x=-2
Hope this helps!
Thanks!
Have a great day!
 
        
             
        
        
        
Since these both are on the same hour we'll ignore the 5. We end up having :35 and :52. We'll subtract 35 from 52 which gives us 17. The answer to this is 17 minutes.
