Answer:
Is this an exam? looks like it
Answer:
The correct answer is YES, it is a solution of the system.
Step-by-step explanation:
The system of equations have equations 2x − 3y = −5 and 4x − 4y = −4.
We need to find whether of not (2,3) is a solution to the system of equation.
We multiply the equation 2x − 3y = −5 by 2 and subtract it with the other equation. This gives us,
⇒ 4x - 6y +10 -4x +4y -4 = 0
⇒ 2y = 6
⇒ y = 3.
⇒ x = 2.
Thus ( 2 , 3 ) is the solution.
Let x = price of shoes
Then price of jacket would be x - 5.81
Combining the two would give you
x + x - 5.81 = 99.15
combining like terms simplifies to 2x - 5.81 = 99.15;
now adding 5.81 to both sides of the equal sign leaves
2x = 104.96
and finally, dividing both sides by 2, gives x = $52.48; which is the cost of the shoes. Recall, the cost of the jacket is 5.81 less than the cost of the shoes.
so, COST OF THE JACKET is 52.48 - 5.81 = $46.67
