choose an equivalent system of equations to the following system:
fx + gy = h
qx + ry = s

a. 5fx + 5gy = 5h
qx − ry = s

b. 5fx + gy = 5h
qx + 5ry = s

c. 5fx + 5gy = 5h
qx + ry = s

d. fx + 5gy = 5h
qx + ry = s

An equivalent system of equations is the option C

Step-by-step explanation:

we have the following system

-----> equation A

-----> equation B

Remember that

The Multiplication Property of Equality states that if you multiply both sides of an equation by the same number, the sides remain equal

so

Multiply the equation A by 5 both sides

Distributive property

----> equation C

Now we have the equivalent system of equations

----> equation C

-----> equation B

therefore

An equivalent system of equations is the option C
