Answer:
x = - 
Step-by-step explanation:
 (x - 3) - 5 =
 (x - 3) - 5 =  (x - 1)
 (x - 1)
Multiply through by 8 to clear the fractions
 6(x - 3) - 40 = x - 1 ← distribute parenthesis and simplify left side
6x - 18 - 40 = x - 1
6x - 58 = x - 1 ( subtract x from both sides )
5x - 58 = - 1 ( add 58 to both sides )
5x = - 57 ( divide both sides by 5 )
x = - 
 
        
             
        
        
        
Answer:
(x, y) = (-1, 1)
Step-by-step explanation:
8x + y = −7 
for y = 1
8x + 1 = -7
subtract 1 from boh sides
8x = -8
divide bot sides by 8
x = -1
(x, y) = (-1, 1)
 
        
             
        
        
        
    4(x - 4) + 65 = -3x
4(x) - 4(4) + 65 = -3x
     4x - 16 + 65 = -3x
            4x + 49 = -3x
          - 4x           - 4x
                    49 = -7x
                    -7      -7
                     -7 = x
