1) -3(5x+2y=-3)⇒ -15x-6y=9
⇒ -9x=27
2(3x+3y=9)⇒ 6x+6y=18
2) -9x/-9=27/-9 ⇒ x=-3
3) 3(-3)+3y=9⇒ -9+9+3y=9+9⇒ 3y/3=18/3⇒ y=6
Answer: (-3,6)
Reasoning:
Step 1) In order to eliminate, first I had to multiple the first equation by -3 and the second by 2 so that when combining the equations y would cancel each other out so that I could solve for x. <em>Note: There are many combinations as to how you could multiple the equations so that either the x or y would cancel out.
</em>
Step 2) Once y is eliminated, solve for x.
Step 3) Now plug x back into one of the original equations and solve for y. <em>Note: Plug x back into one of the original equations, not the equations that were changed by multiplication,</em>
32.00=3 tens 2 ones 30+2=32

Answer:
2 multiply by six is 12
Step-by-step explanation:
this answer is not correct
the answer would be -12 as the biggest no. is 6 and it contains - sign

Answer:
VF= $3.281,42
Interes= 3.281,42 - 3.000= $281.42
Step-by-step explanation:
Dada la siguiente información:
Prestamo (P)= $3.000
Tasa (i)= 0,015/2= 0,0075
Cantidad de periodos (n)= 6*2= 12 semestres
<u>Para calcular el valor final del prestamos, tenemos que usar la siguiente formula:</u>
VF= P*(1 + i)^n
VF= 3.000*1,0075^12
VF= $3.281,42
Interes= 3.281,42 - 3.000= $281.42
