5(5t - 2) = -35

OpenStudy (anonymous):

well i dont really know how to do it at all

OpenStudy (anonymous):

I guess youre looking for the value of t? You have to isolate the t.

OpenStudy (anonymous):

ok then what do you do next ?

OpenStudy (anonymous):

Ok, you want to take the t on the left side of the "=" and the rest of the numbers to the right: First, divide both sides by 5 \[\frac{ 5(5t - 2) }{ 5}=\frac{ -35}{ 5 } \] ok, try it

OpenStudy (anonymous):

thank you soo much !! do you do that when your solving multi-step equations to ??

OpenStudy (anonymous):

Yes, you have to isolate the variable; in your previous example you divide by 5 to get rid of the 5, multiplying (5t-2)then you only have to move the other 5 and the -2 to get the value of t.

OpenStudy (anonymous):

I think your example is multi-step though

OpenStudy (anonymous):

thank you can you pleasee write it out in letters because i dont really understand !

OpenStudy (anonymous):

Ok, after dividing by 5 you get \[5t-2=-7\] Then you add 2 on both sides \[5t-2+2=-7+2\] You get: \[5t=-5\] Divide by 5 again: \[\frac{ 5t }{ 5}=\frac{ -5 }{ 5 }\] So you get the answer: \[t=-1\]

thank you can u please help me wit this also -----> 60 = 6 (6 - 20 )

OpenStudy (anonymous):

60=6(6-20) \[60= 6(-14) =-8\] 60 = -84 So, that equation doesn't have a solution.

OpenStudy (anonymous):

the number up there was supposed to be -84, not -8

OpenStudy (anonymous):

ughhh lol i didnt write it write i was supposed to write 60 =6(6-2n)
