Answer:
Hi! The correct answer is x = -1 y = -1 and the ordered pair is (-1,-1)
Step-by-step explanation:
<em><u>~Solve the first variable in one of the equations, then substitute the result into the other equation~</u></em>
In the science class,
there are 3 girls and 1 boy (grade 7)
and 5 girls and 5 boys (grade 8)
There is a total of 14 pupils being 8 girls and 6 boys
The probability of choosing a boy will be

Which can be simplified into

by
dividing 2 from the numerator as well as the denominator.
Step-by-step explanation:
Vamos resolver sua equação passo a passo.
10-7c=10+2(3-5c)
Etapa 1: simplifique os dois lados da equação.
10-7c=10+2(3-5c)
10+-7c=10+(2)(3)+(2)(-5c)(Distribuir)
10+-7c=10+6+-10c
-7c+10=(-10c)+(10+6)(Combine os termos semelhantes)
-7c+10=-10c+16
-7c+10=-10c+16
Etapa 2: adicione 10c a ambos os lados.
-7c+10+10c=-10c+16+10c
3c+10=16
Etapa 3: subtraia 10 de ambos os lados.
3c+10-10=16-10
3c=6
Etapa 4: divida os dois lados por três.
3c
3
=
