-2(x+2/3)+1=5 Please somebody help me out there in brainly land
Harrizon [31]
X=-1.8
To solve first use the distributive property to change the equation to -2x+1 1/3+1=5
Then you subtract 1 from 5 so then the equation looks like this: -2x+1 1/3=4
Next subtract 1 1/3 from 4 to get 3.6
then divide it by -2 and you get -1.8

What error did zacharias make?

Quadratic formula as x = ; substitution as x

The errors he made: he mistakenly used the negative (-) and postive (+)
      * -5 should have been 5
      * 52 should have been -52
      * both the numerator and the denominator  should have been -2 instead        of 2
