Question

Rezolvați ecuațiile:
a)24,43-x=8,938;
b)7,28+x=132,57;
c)x-37,5=132,04;
d)x+4=27,5.

Answer 1

Explicație pas cu pas:

a)

$24,43-x=8,938 \\ x = 24,43 - 8,938 \\ x = 15,492$

b)

$7,28+x=132,57 \\ x = 132,57 - 7,28 \\ x = 125,29$

c)

$x-37,5=132,04 \\ x = 132,04 + 37,5 \\ x = 169,54$

d)

$x+4=27,5 \\ x = 27,5 - 4 \\ x = 23,5$
