460 + 85 x 4 = \(\frac{X+175}{5}\) + 30

GIAI THEO CACH LOP 5

Answer 1

\(460+85\) x \(4=\frac{x+175}{5}+30\)

 \(460+340=\frac{x+175}{5}+30\)

\(800=\frac{x+175}{5}+30\\ \frac{x+175}{5}=800-30\\ \frac{x+175}{5}=770\)

\(x+175=770\) x \(5\)

\(x+175=3850\\ x=3850-175\\ x=3675\)

 

Answer 2

460 - 80 x 4 = ( x + 200) : 4
460 - 340 = (x + 200) : 4
120 = ( x + 200) : 4
x + 200 = 120 x 4
x + 200 = 480
          x = 480 - 200
          x = 280
