ayuda si me ayudan doy corona

Answer 1

PROBLEMA 1

$4x + x - 1 = 4 + 10 \\ 5x - 1 = 14 \\ 5x = 14 + 1 \\ 5x = 15 \\ x = \frac{15}{5} \\ x = 3$

PROBLEMA 2

$4x - 2 + 3x = 3x + x + 7 \\ 7x - 2 = 4x + 7 \\ 7x - 4x = 7 + 2 \\ 3x = 9 \\ x = \frac{9}{3} \\ x= 3$

PROBLEMA 3

$8x - 4 + 3x + 4x - 2 + 3 + x = 7x + x + 14 \\ 16x - 6 = 8x + 14 \\ 16x - 8x = 14 + 6 \\ 8x = 20 \\ x = \frac{20}{8} \\ x = 2.5$

PROBLEMA 4

$3 - 15 + 9x - 15 + 5x + 5x + 6 = x + 3 + x + 9 + 8x - 15 + 10x + 5 \\ 19x - 21 = 20x + 2 \\ - 21 - 2 = 20x - 19x \\ - 23 = x$
