Q. what will be the number if we subtract

40

from

3

times of the number and the result is

170

Define Unknown Number: Let's denote the unknown number as $x$ . According to the problem, $3$ times the number minus $40$ equals $170$ . We can write this as an equation: $3x - 40 = 170$ .
Write Equation: To find the value of $x$ , we need to isolate it on one side of the equation. First, we add $40$ to both sides of the equation to get rid of the $-40$ on the left side. This gives us $3x = 170 + 40$ .
Add $40$ : Now we perform the addition on the right side of the equation: $170 + 40 = 210$ . So, we have $3x = 210$ .
Perform Addition: To solve for $x$ , we divide both sides of the equation by $3$ . This gives us $x = \frac{210}{3}$ .
Divide by $3$ : Performing the division, we find that $210$ divided by $3$ equals $70$ . So, $x = 70$ .
