a) 234-x/3=174

b) (147-x)/3=10

Answer 1

[ミ★๖ۣۜSεηαbĭ ๖ۣۜTĭʂт ๖ۣۜKεү ★彡]

\(a,234-\frac{x}{3}=174\)

\(\frac{x}{3}=60\)

\(x=180\)

\(b,\frac{\left(147-x\right)}{3}=10\)

\(\Rightarrow147-x:3=10\)

\(x:3=137\)

\(x=411\)

Answer 2

[๖ۣۜƝƘ☆❖TྂRí❖TIêNྂᴾᴿᴼAK❖47シRồng lửa]

a)\(234-\frac{x}{3}=174\)

\(\frac{x}{3}=234-174\)

\(\frac{x}{3}=60\)

\(\Rightarrow x=3.60\)

\(\Rightarrow x=180\)

b)\(\frac{\left(147-x\right)}{3}=10\)

\(\frac{\left(147-x\right)}{3}=\frac{10}{1}\)

\(\Rightarrow\left(147-x\right)=3.10\)

\(\Rightarrow\left(147-x\right)=30\)

\(\Rightarrow x=147-30\)

\(\Rightarrow x=117\)
