Question

c) 0,5m - 24 = 1.1m + 6
d) 2.3x + 29 = 0.3x - 7

f) 5x + 4x + 6 = 2x + 9x + 10 g) 3h + 1 + 2h = 5h – 23 + 2h
h) 5w -8 + 3w + 10 = 8W + 11-30​

Answer 1

c)

$0.5m - 24 = 1.1m + 6 \\ - 24 - 6 = 1.1m - 0.5m \\ - 30 = 0.6m \\ \frac{ - 30}{0.6} = m \\ - 50 = m$

d)

$2.3x + 29 = 0.3x - 7 \\ 2.3x - 0.3x = - 7 - 29 \\ 2x = - 36 \\ x = \frac{ - 36}{2} \\ x = - 18$

f)

$5x + 4x + 6 = 2x + 9x + 10 \\ 9x + 6 = 11x + 10 \\ 6 - 10 = 11x - 9x \\ - 4 = 2x \\ \frac{ - 4}{2} = x \\ - 2 = x$

g)

$3h + 1 + 2h = 5 - 23 + 2h \\ 5h + 1 = - 18 + 2h \\ 5h - 2h = - 18 - 1 \\ 3h = - 19 \\ h = \frac{ - 19}{3} \\ h = - 6.3$

h)

$5w - 8 + 3w + 10 = 8w + 11 - 30 \\ 8w + 2 = 8w - 19 \\ 8w - 8w = - 19 - 2 \\ 0 = 0 \\ las \: varariables \: se \: cancelan$
