3t-18t+4=-26
first you want to move the 4 to the other side of the equation so subtract that from both sides of the equation which gives you this 3t-18t=-30.
Next you would combine the like terms that are on the left side of the equation giving you -15t=-30. Now you want t by itself so you divide both sides by -15 which would give you t=2
Divide the numerator and denominator by 3:
15 / 3 = 5
24 / 3 = 8
5/8

Step-by-step explanation:
We are given the expression: "15 more than a number"
By the look of the answer choices, we want to convert this sentence into a mathematical formula.
We do this by starting off with a key word, "more". More would imply <em>addition</em>. Hence, we would be adding 15 to some number. We can define some number to be <em>x</em> to get us our answer:
15 + x
Which is answer choice B.
