Pls solve the simultaneous equation in the attachment.

Part a) The solution is the ordered pair (6,10)

Part b) The solutions are the ordered pairs (7,3) and (15,1.4)

Step-by-step explanation:

Part a) we have

----> equation A

----> equation B

Multiply equation A by 10 both sides to remove the fractions

----> equation C

isolate the variable y in equation B

----> equation D

we have the system of equations

----> equation C

----> equation D

Solve the system by substitution

substitute equation D in equation C

solve for x

Multiply by 3 both sides

Combine like terms

Find the value of y

The solution is the ordered pair (6,10)

Part b) we have

---> equation A

----> equation B

isolate the variable x in the equation B

----> equation C

substitute equation C in equation A

solve for y

Solve the quadratic equation by graphing

The solutions are y=1.4, y=3

see the attached figure

Find the values of x

For y=1.4

For y=3

therefore

The solutions are the ordered pairs (7,3) and (15,1.4)
