How do I solve 15-4t=3 because when I tried to solve it kept becoming negative and how would it become positive from negative when you divide a positive and a negative because the output between that is always negative?

15-4t -15 = 3-15" "154t15=315 leaving you with

-4t=-12.4t=12.

22. Divide by -44 to isolate t .

t=(-12)/-4t=124

3.3. Answer is t=3t=3

t=3t=3

Explanation:

15-4t=3154t=3

15-15 -4t=3 -1515154t=315

t=3t=3

Explanation:

color(white)(xxxx)15color(blue)(-4t) =3" "larr××154t=3 add 4t4t to both sides

15-4t+4t = 3color(blue)(+4t)154t+4t=3+4t

The term in tt is now positive on the right. Isolate it.

15color(white)(xxxxxxx)=3color(blue)(+4t)" "larr15×××x=3+4t subtract 33 from both sides

15-3color(white)(xxxx) = 3+4t-3153××=3+4t3

12color(white)(xxxxxxx) = 4t" "larr12×××x=4t divide by 44

3color(white)(xxxxxxxx)=t3××××=t
