I have these on my study guide but for some reason I keep getting them wrong can someone break it down for me.
1. 2+4(x7)=75(x4)
2. 2(5z1)2(z+9)=3(z+1)
This one is a fraction:
5/9x+2/3=5/9

Best ResponseYou've already chosen the best response.01. 2 + 4x  28 = 7  5x + 20 4x  26 = 27  5x +5x +5x  9x  26 = 27 + 26 +26  9x = 53 x = 53/9

Best ResponseYou've already chosen the best response.0Problem 2. 2(5z1)2(z+9)=3(z+1) 10z22z18=3z+3 < correct 8z20=3z+3 < correct +20  8z=3z+23 < correct 3 < should read 3z 5z=23 /5 23/5=z < correct final answer

Best ResponseYou've already chosen the best response.0For the third one is it like this with the x beside 5/9? just want to make sure it's not in the denominator \[\frac{ 5 }{ 9 }x+\frac{ 2 }{ 3 }=\frac{ 5 }{ 9}\]

Best ResponseYou've already chosen the best response.0The answer is correct. Do they ask for a decimal instead of a fraction?

Best ResponseYou've already chosen the best response.2Yes peachpi and it ask for a integer or simplified fraction

Best ResponseYou've already chosen the best response.0ok. you can do the same thing you did for the others. Start by subtracting 2/3 from both sides, then you'll need to get a common denominator to subtract the fractions. dw:1439177420232:dw

Best ResponseYou've already chosen the best response.2ok do I find the common denominator on both fractions or just change one?
