Answer:
Step-by-step explanation:
you just need to add both equations
you will get 3y=12+6=18
3y=18
y=6
now replace y=6
3x+12=6
3x=6-12
3x=-6
x=-2
(-2,6)
 
        
                    
             
        
        
        
4 5/12 you just add the fractions

Answer:
m=8
Step-by-step explanation:
-88=-3(4m+5)-(1-3m)
-88=-12m-15-(1-3m)   <- Distributive Property
-88=-12m-15-1+3m  <- Open () if there is a negative negative the symbol equals positive
-88=-9m-16    <- Simplify
0=-9m+72   <- Add 88 to both sides
9m = 72 <- Add 9m to both sides
9m = 72
/9      /9
m=8
