Simplifying
3x + 4 = 7 + -2x
Reorder the terms:
4 + 3x = 7 + -2x
Solving
4 + 3x = 7 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
4 + 3x + 2x = 7 + -2x + 2x
Combine like terms: 3x + 2x = 5x
4 + 5x = 7 + -2x + 2x
Combine like terms: -2x + 2x = 0
4 + 5x = 7 + 0
4 + 5x = 7
Add '-4' to each side of the equation.
4 + -4 + 5x = 7 + -4
Combine like terms: 4 + -4 = 0
0 + 5x = 7 + -4
5x = 7 + -4
Combine like terms: 7 + -4 = 3
5x = 3
Divide each side by '5'.
x = 0.6
Answer: x = 0.6
Answer:
1.95
Step-by-step explanation:
Answer: The probability that the no. is divisible by 4 is 0.225 .
Step-by-step explanation:
First three-digit number: a = 100
Last digit number: l = 996
Common difference: d = 4
Formula: l=a+(n-1)d
Substitute all values, we get

i.e. there are 225 three digit numbers divisible by 4.
Total 3-digit numbers = 1000
The probability that the no. is divisible by 4 = 
Hence, the probability that the no. is divisible by 4 is 0.225 .
