 Question 19511: Hi, I am stuck somewhere in here, can anybody point me back to the proper path? Thanks, I am solving for a linear system with 3 variables 2x+3y-4z=4 x-6y+z=-16 -x+3z=8 I multiplied the first equation by 2 and got 4x+6y-8z=8 I then added this to the second and got a answer of 5x-7z=-8 I then multiplied the third equation by 5 and got z=4 but then I just petered out from here.... Any help would be great, Thanks sloozy Click here to see answer by stanbon(57984)

 Question 24045: It has been 7 years since my last algebra class. The answer is 8 but I am not sure how to solve this problem can you please help me : 2/3(x+6)=1+ (4x-7)/3 I have tried common denominator of 6 4(x+6)= 1+2(4x-7) 4x+24=1+8x-14 4x+24=8x-13 stuck here I tried 3 as common denominator also 3(x+6)= 1+3(4x-7) 3x+18 = 16x-28 -13x=-46 stuck here Click here to see answer by rapaljer(4667)
