Question

Afla nr necunoscut din expresiile 22-5×(38-4×g)=12

Answer 1

Răspuns: $\pink{\underline{\bf g=9}}$

Explicație pas cu pas:

$\bf 22-5\cdot(38-4\cdot g)=12$

$\bf 22=12+5\cdot(38-4\cdot g)$

$\bf 22-12=5\cdot(38-4\cdot g)$

$\bf 10=5\cdot(38-4\cdot g)$

$\bf 10:5=38-4\cdot g$

$\bf 2=38-4\cdot g$

$\bf 2+4\cdot g=38$

$\bf 4\cdot g=38-2$

$\bf 4\cdot g=36$

$\bf g=36:4$

$\pink{\underline{\bf g=9}}$
