Question

Which ordered pair is the solution to the system of equations? {y=2x−154x+3y=−5 (5, −5) (7, −11) (4, −7) (0, 6)

Answer 1

y=2x−15

4x+3y=−5

_________

4x+3(2x-15)= -5

4x+6x-45= -5

10x=-5+45

10x= 35

X=35/10

X= 3.5 or 3 and 1/2

Now solve for y

4x+3y=−5

4(3.5)+3y= -5

12.5+3y= -5

.40+3y= -5

3y= -5-0.40

3Y= -5.40

Y= -1.80

Answer (3.5, -1.80)

Answer 2

So that you all don't have to go and do extra work the answer is (4, -7) :)
