Answer:
Therefore first number is 3 and second number is 18
Step-by-step explanation:
Sum of the two numbers is 21 and Second number is six times the first number
x+6x = 21
7x = 21
x = 21/7
x = 3
substitute x value in 6x to find second number,
= 6x
= 6*3
= 18
I believe the answer is 6.
25-4x=15-3x+10-x is all real numbers. You must simply both sides of the equation. The problem is then -4x+25= -4x+25 which is the same. If this happens the answer is always all real numbers.
The number is 5; 5*8=50, 40-5=35
