75 + 2t = 100 - 2t
75 + 4t = 100
4t = 25
t = 25/4 = 6(1/4)
Check:
left hand side = 75 + 2 x 25/4 = 75 + 25/2 = 87(1/2)
right hand side = 100 - 2 x 25/4 = 100 - 25 /2 = 87(1/2)

75+2t=100-2t
2t+2t=100-75
4t= 25
t=25/4
= 6.24

75+2t=100-2t
75+2t+2t=100-2t+2t=100
75+4t-75=100-75=25
4t=25, t=25/4, therefor t=6.25
check
75+2*6.25=87.5
100-2*6.25=87.5

well im ot entirely sure
i had a go at it
75 plus 2 times summit gets u 100
so 2 times 7.5 gets u 15 and 75 plus 15 gets u 100
therefore T is 7.5
100-2t (7.5) = i dunno
i like maths but this sort of stuff is realy hard
