Question

3-( X+4)+X=2X-3 AYUDENME PORFIS

Answer 1

Explicación paso a paso:

$3 - (x + 4) + x = 2x - 3 \\ 3 - x - 4 + x = 2x - 3 \\ - 1 = 2x - 3 \\ - 2x = - 3 + 1 \\ - 2x = - 2 \\ x = 2 \div 2 \\ x = 1 \\ \\ comprobación \\ 3 - (1 + 4) + 1 = 2 \times 1 - 3 \\ 3 - 5 + 1 = 2 - 3 \\ - 2 + 1 = - 1 \\ - 1 = - 1$
