Question

rezolva ecuatiile:
25,3+3x=47,95

x-251,1=10,22

x+43,27=2x-1,01

Answer 1

Explicație pas cu pas:

$\bf 25.3 + 3x = 47.95 \\ \\ \bf 3x = 47.95 - 25.3 \\ \\ \bf 3x = 22.65 \\ \\ \bf x = 22.65 \div 3 \implies \red{\boxed{\bf x = 7.55}}$

$\space$

$\bf x - 251.1 = 10.22 \\ \\ \bf x = 10.22 + 251.1 \implies \blue{\boxed{\bf x = 261.32}}$

$\space$

$\bf x + 43.27 = 2x - 1.01 \\ \\ \bf x - 2x = -1.01 - 43.27 \\ \\ \bf -x = -44.28 \implies \green{\boxed{\bf x = 44.28}}$
