To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the > sign and the answer on the other.

3y + 3 > -4 + 5y
3y > -4 + 5y - 3
3y - 5y > -4 - 3
-2y > -7
y > \( \frac{-7}{-2} \)
y > 3\(\frac{1}{2}\)

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

6a³ - 8a³ = -2a³

The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:

c = πd
c = π(2 * r)
c = π(2 * 8)
c = 16π

To solve this equation, isolate the variable for which you are solving (b) on one side of the equation and put everything else on the other side.

5b + 6x = 3b + x + 2
5b = 3b + x + 2 - 6x
5b - 3b = x + 2 - 6x
2b = -5x + 2
b = \( \frac{-5x + 2}{2} \)
b = \( \frac{-5x}{2} \) + \( \frac{2}{2} \)
b = -2\(\frac{1}{2}\)x + 1
