\(\dfrac{x}{60}+ \dfrac{x}{45}+1,5=\dfrac{32}{5}\)

Answer 1

\(x=126\)

Answer 2

x/60 + x/45 + 1,5 = 32/5

3x + 4x + 270 = 1152

7x + 270 = 1152

7x = 1152 − 270

7x = 882

x = 882/7

x = 126

Answer 3

\(\dfrac{x}{60}+\dfrac{x}{45}+1,5=\dfrac{32}{5}\)

\(\Leftrightarrow\)​​​\(\dfrac{x}{60}+\dfrac{x}{45}+\dfrac{3}{2}=\dfrac{32}{5}\)​

\(\Leftrightarrow\dfrac{3x}{180}+\dfrac{4x}{180}+\dfrac{270}{180}=\dfrac{1152}{180}\)

\(\Leftrightarrow7x+270=1152\)

\(\Leftrightarrow7x=882\)

\(\Leftrightarrow x=126\)

Answer 4

x=126
