Question

Qual a resposta das equações:

2x + 2 = 12

2 + x - 10 + x = 8

Answer 1

Resposta:

Explicação passo-a-passo:

2x + 2 = 12

2x = 12- 2

2x = 10

X = 10/2

X = 5

2 + x - 10 + x = 8

2x - 8 = 8

X = 16/2

X = 8

Answer 2

$\large\boxed{\begin{array}{l}\sf 2x+2=12\\\sf 2x=12-2\\\sf 2x=10\\\sf x=\dfrac{10}{2}\\\\\sf x=5\end{array}}$

$\large\boxed{\begin{array}{l}\sf 2+x-10+x=8\\\sf x+x=10+8-2\\\sf 2x=16\\\sf x=\dfrac{16}{2}\\\\\sf x=8\end{array}}$
