Question

A raiz da equação 2(x+5)-3(5-x)=5 é:

Answer 1

Resposta:  2

Explicação passo a passo:

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

2x+10-15+3x=5

2x+3x=5-10+15

5x=10

x=10/5

x=2

Answer 2

$\LARGE\tt{}2\left(x + 5\right) - 3\left(5 - x\right) = 5 \\ \\ \LARGE\tt{}2x + 10 - 3\left(5 - x\right) = 5 \\ \LARGE\tt{}2x + 10 - 15 + 3x = 5 \\ \LARGE\tt{}5x + 10 - 15 = 5 \\ \LARGE\tt{}5x - 5 = 5 \\ \LARGE\tt{}5x = 5 + 5 \\ \LARGE\tt{}5x = 10 \\ \\ \LARGE\tt{}x = \dfrac{10}{5} \\ \\ \\ \LARGE\tt{}x = 2 \\ \\\LARGE\tt{} s \{x = 2 \}$
