Question

me ayudan con estas ecuaciones) a)x:26=8 b)2x+3x=35

C)3²+x+5-2=50
d) (5+1)²-3²+x=35

Answer 1

a)
$\frac{x}{26} = 8 \\ x = 208$
b)
$2x + 3x = 35 \\ 5x = 35 \\ x = \frac{35}{5} \\ x = 7$
c)
${3}^{2} + x + 5 - 2 = 50 \\ 9 + x + 3 = 50 \\ x + 12 = 50 \\ x = 50 - 12 \\ x = 38$
d)
${(5 + 1)}^{2} - {3}^{2} + x = 35 \\ {6}^{2} - 9 + x = 35 \\ 36 - 9 + x = 35 \\ 27 + x = 35 \\ x = 35 - 27 \\ x=8$
