t - 3.2 + 5.1 = 12
This is a linear equation with one unknown (the number represented by "t")
To solve such an equation perform mathematical operations (addition, subtraction, multiplication and division) so that a single quantity of "t" is on the left hand side of the equation and all other terms on the opposite side.
Add 3.2 to both sides :
t - 3.2 + 3.2 + 5.1 = 12 + 3.2 : t + 5.1 = 15.2
Subtract 5.1 from both sides :
t + 5.1 - 5.1 = 15.2 - 5.1 : t = 10.1

What does b equal in b plus 15 equals 27?
To solve for b in the equation b + 15 = 27, you need to isolate b on one side of the equation. To do this, you can subtract 15 from both sides of the equation. This gives you b = 27 - 15, which simplifies to b = 12. Therefore, b equals 12 in the given equation.
