If t=1, then 5t = 5 and 5t + 5 = 10
5t + 25 = 525 divide by 5 to both sides t + 5 = 105 subtract 5 to both sides t = 100
5t + 2 = 3t - 2t + 5 Collect like terms 5t - 3t + 2t = 5 - 2 4t = 3 t = ¾ Check: 5 x 3/4 = 3¾ + 2 = 5¾; 3x¾- 2x¾ + 5 = 5¾ QED

If t=1, then 5t = 5 and 5t + 5 = 10
5t + 25 = 525 divide by 5 to both sides t + 5 = 105 subtract 5 to both sides t = 100

no answer to t 5t - 5 = 5t +7 ( subtract 5t from both sides reducing to) -5 = +7 Negative 5 does not equal positive 7.
5t - 9 = 26(Add 9 to both sides)5t = 35(Divide both sides by 5)t = 7
