-6z + 5-2(z+1)=3z-2
first do the parentheses:
-6z+5-2z-2=3z-2
Then combine like terms:
-8z+3=3Z-2
Add 8z to both sides of the equation:
3=11z-2
Add 2 to both sides of the equation:
5=11z
Divide both sides by 11
%285%2F11%29=z
check by substituting 5%2F11 for z in the equation:
-6z+%2B+5-2%28z%2B1%29=3z-2
-6%2A%285%2F11%29%2B5-2%2A%285%2F11%2B1%29-2=%283%2A%285%2F11%29%29-2
convert everything to the same denominator to validate:
-6%2A%285%2F11%29%2B%2855%2F11%29-2%2A%28%285%2F11%29%2B%2811%2F11%29%29=3%2A%285%2F11%29-%2822%2F11%29
%28-30%2F11%29%2B%2855%2F11%29-%2832%2F11%29=%2815%2F11%29-%2822%2F11%29
combine like terms:
%28-7%2F11%29=%28-7%2F11%29, So this is correct
