Answer:
Statement: x =15.
Reason: Subtraction and Division properties of equality.
Explanation:
Given: and
⇒
⇒ 60= 3x+15 or
Subtraction property of equality: Subtract the same number from both sides of an equation.
Subtract 15 from both sides of an equation;
or
45=3x
Division property of equality: Divide the same number from both sides of an equation;
Divide by 3 from both sides of an equation, we have
Simplify:
x=15 Hence proved!

Spending money, since your amount of money is decreasing, which is negative
Answer:
x= -2y/3
-4y+4y=14
0y= 14
This has no solution.
Step-by-step explanation:
Answer In cases of two equations having two unknown variables the simultaneous method of solving the equations is adopted.
Supposing “0” as the value of “k” we will have the equation as 3x+2y=0
Then separating variable x will give, x= -2y/3
Substituting the value of x into the first equation that is: 6x + 4y = 14
6(-2y/3)+4y=14
Expanding this we get: 6(-2y/3)+4y=14
-4y+4y=14
0y= 14
Thus, no solution.
