The answer is .6 repeating.
        
             
        
        
        
You simply plug in the value of x in each equation to find y.
1)
y = 7 - 3(2)
y = 7 - 6
y = 1
2)
y = 18/2
y = 9

Rewriting this <span>7-y=5x+11 in standard form involves only changing the order in which the terms appear:
</span><span>7-y=5x+11 becomes 5x + y  + 11 - 7 = 0, or 5x + y + 4 = 0, or 5x + y = -4.</span>
        
             
        
        
        
The LCM of 6 and 15 is 30:)
