-4(t+10)<48
=> t + 10 > - 12
(whenever an inequality is multiplied or divided by a negative number, it changes; < becomes >)
=> t > -22

-4t -40 <48. what ever maximum value we will give to t it will be always in negetive side. So -4t-40 is always less than 48.

-4t-40=48
then add forty both sides
-4t = 88
divide both sides by -4
t = -22
then always do a final check go -22 + 10
is -12
-4 x -12 = 48

multiply (-4) into t and 10
so it would be -4t +(-40)< 48
add negotive 40 from both sides
-4t<88
devide -4 into 88
and t > -22
the greater than singh will always be opposite
at the answer

-4(t+10)<48
-4t - 40 <48
-40 -48<4t
-88<4t
-22
ie t>-22
Ans: t lies in interval (-22, infinity)

I take it you are trying to solve for t in the equation? The solution must be less than 48. So t will be a series and not a value.
Would need the full equation to evaluate (ie: real numbers, imaginary numbers, integers, etc)

multiply out the bracket
-4t - 40 < 48
add 40
-4t < 88
divide by 4
-t < 22
times by -1 (remeber to change the sign)
t > -22
Done!
