33,871,648 = (3 x 10^9) + (3 x 10^8) + (0 x 10^7) + (8 x 10^6) + (7 x 10^5) + (1 x 10^4) + (0 x 10^3) + (6 x 10^2) + (4 x 10^1) + (8 x 10^0)
It is an equation in one variable.
The problem |x|-5=3 is an absolute value equation. to find what x equals you have to get x by itself by adding 5 to each side. |x|-5=3 +5 +5 |x|=8 |x| is equal to 8, but is also equal to -8 because the absolute value bars mean that anything inside them is turned positive. Check your answer by substituting 8 and -8 in for x. |8|-5=3? |-8|-5=3?
To find the value of x in the equation x * 3 = 30, you need to isolate x by dividing both sides of the equation by 3. This will give you x = 30 / 3, which simplifies to x = 10. Therefore, the value of x that satisfies the equation x * 3 = 30 is 10.
