If 3x - 8 = 31 find the value of 4x
Can you find the value of x by solving the equation?
I'll be glad to check your answer.
This is sipmle,
3x - 8 = 31
3x - 8 +8 = 31+8 (add 8 both side)
3x = 39 (divide by 3 both side)
x = 13
Then the value of 4x = 4(13) = 52
To find the value of 4x, we first need to find the value of x by solving the equation 3x - 8 = 31.
Step 1: Add 8 to both sides of the equation:
3x - 8 + 8 = 31 + 8
This simplifies to:
3x = 39
Step 2: Divide both sides of the equation by 3:
3x/3 = 39/3
This simplifies to:
x = 13
Now that we have found the value of x, we can substitute it back into the expression 4x to find the value of 4x.
Step 3: Substitute the value of x into the expression 4x:
4(13) = 52
Therefore, the value of 4x is 52.
