COULD YOU JUST PUT ONE OF HE QUESTIONS ON HERE i CAN'T GET IN TO IT SORRY FOR THE CAPS

OpenStudy (anonymous):

No prob, gimme a sec lol.

OpenStudy (anonymous):

Solve the system by substitution. -4.5x - 2y = -12.5 3.25x - y = -.075 Please show your work!

OpenStudy (anonymous):

It isn't a multiple choice question, so unfortunately there are no 'choices.' Instead, I have to type it into a workpad.

OpenStudy (taybabycakes):

OK i CAN HELP

OpenStudy (taybabycakes):

IS THIS ALEGBRA

OpenStudy (anonymous):

Algebra 2, yes.

OpenStudy (anonymous):

I'm sorry, but I have to step away for about 20 minutes. If you could solve it, that'd be wonderful! I'll brb!

OK HERE IS SOME OF THE FIRST PIECE Let's solve for x. −4.5x−2y=−12.5 Step 1: Add 2y to both sides. −4.5x−2y+2y=−12.5+2y −4.5x=2y−12.5 Step 2: Divide both sides by -4.5. −4.5x −4.5 = 2y−12.5 −4.5 x=−0.444444y+2.777778 Answer: x=−0.444444y+2.777778

HERE'S YOUR ANWERS Problem: Solve −4.5x−2y=−12.5;3.25x−y=−0.075 Steps: I will try to solve your system of equations. 3.25x−y=−0.075;−4.5x−2y=−12.5 Step: Solve3.25x−y=−0.075for y: 3.25x−y+−3.25x=−0.075+−3.25x(Add -3.25x to both sides) −y=−3.25x−0.075 −y −1 = −3.25x−0.075 −1 (Divide both sides by -1) y=3.25x+0.075 Step: Substitute3.25x+0.075foryin−4.5x−2y=−12.5: −4.5x−2y=−12.5 −4.5x−2(3.25x+0.075)=−12.5 −11x−0.15=−12.5(Simplify both sides of the equation) −11x−0.15+0.15=−12.5+0.15(Add 0.15 to both sides) −11x=−12.35 −11x −11 = −12.35 −11 (Divide both sides by -11) x=1.122727 Step: Substitute1.122727forxiny=3.25x+0.075: y=3.25x+0.075 y=(3.25)(1.122727)+0.075 y=3.723864(Simplify both sides of the equation) Answer: y=3.723864 and x=1.122727

OpenStudy (taybabycakes):

are you there

OpenStudy (anonymous):

Ah sorry! I just got back!

OpenStudy (anonymous):

Wait...it's supposed to be 0.75 and not 0.075 :c

OpenStudy (taybabycakes):

yes

OpenStudy (taybabycakes):

I mean't no

OpenStudy (anonymous):

Yeah! On my school site it says -0.75 and not -0.075

OpenStudy (taybabycakes):

that's what I said

OpenStudy (taybabycakes):
