24.524.5

Explanation:

54 = 17 + (10t)/7 + 254=17+10t7+2

35 = (10t)/735=10t7

t = 3.5 * 7t=3.57

t=24.5t=24.5

Explanation:

Start by adding the numbers on the right-hand side:

5.4= 1.7+0.2 + (t/7)5.4=1.7+0.2+(t7)

You get,

5.4= 1.9 +(t/7)5.4=1.9+(t7)

Take the 1.91.9 to the other side and flip the sign.

5.4-1.9=(t/7)5.41.9=(t7)

Subtract,

3.5=(t/7)3.5=(t7)

Since tt is being divided by 77 in the fraction, 77 will go by multiplication,

3.5 xx7=t3.5×7=t

Multiply the numbers,

24.5=t 24.5=t

OR

t=24.5t=24.5
