Question

Calcula el valor de x: a) 2x+3=2 b)2x-5=x-10 c) 6(x+1)+18=60 d) 3(x-3)=2x+2 ayuda pls

Answer 1

a)
$2x + 3 = 2 \\ 2x = 2 - 3 \\ 2x = - 1 \\ x = - 1 \div 2 \\ x = - 0.5$
b)
$2x - 5 = x - 10 \\ 2x - x = - 10 + 5 \\ x = - 5$
c)
$6(x + 1) + 18 = 60 \\ 6x + 6 + 18 = 60 \\ 6x + 24 = 60 \\ 6x = 60 - 24 \\ 6x = 36 \\ x = 36 + 6 \\ x = 6$
d)
$3(x - 3) = 2x + 2 \\ 3x - 9 = 2x + 2 \\ 3x - 2x = 2 + 9 \\ x = 11$
