Question

Calcule a equação 3 + 1/2 (x/4 + 8) = 1/4 (2x - 5)

Answer 1

Resposta:

Explicação passo a passo:

3 + 1/2 (x/4 + 8) = 1/4 (2x - 5)

" 3 + x/8 +8/2 = 2x/4 - 5/4 ""

" 3+4+x/8= x/2 - 5/4"

"7+x/8 = (2x-5)/4"

(56+x)/8 = (2x-5)/4"

"(56+x)/2 = (2x-5)"

*'56+x= 2.(2x-5)"

"56+x= 4x-10'

"56+10= 4x-x"

"66= 3x"

66/3= x"

"x= 22"
