Answer:
x = 12
Step-by-step explanation:
This equation is very easy to solve.
3x - 13 = 23 Add 13 to both sides of the equation.
3x = 36 Divide by 3 on both sides of the equation.
x = 12
Then, check your answer by substituting the solved value.
3(12) - 13 = 23
36 - 13 = 23
23 = 23
Therefore, x = 12 is the solution to the equation.

Answer:
78 x 10² or 7.8 x 10³
Step-by-step explanation:
you have to get the exponents the same before you can subtract the coefficients
8 x 10³ = 80 x 10²
80 x 10² - 1.7 x 10² = 78 x 10² or 7.8 x 10³
