Question

x-36:18+2.x+5=19+2.{x-1}

Answer 1

x-36/18+2.x+5=19+2.(x-1)

x-2+2x+5=19+2x-1.2

3x-2+5=2x-2+19

3x+3=2x+17

3x=2x+14

x=14

Answer 2

\(x-36:18+2.x+5=19+2\left(x-1\right)\)

\(\Leftrightarrow x+2x+5-\frac{36}{18}=19+2\left(x-1\right)\)

\(\Leftrightarrow3x+5-\frac{38}{16}=19+2\left(x-1\right)\)

\(\Leftrightarrow3x+5-2=19+2\left(x-1\right)\)

\(\Leftrightarrow3x+3=19+2\left(x-1\right)\)

\(\Leftrightarrow3x+3=2x+17\)

\(\Leftrightarrow3x=2x+17-3\)

\(\Leftrightarrow3x=2x+14\)

\(\Leftrightarrow3x=2x+14-2x\)

\(\Leftrightarrow x=14\)

=> x = 14
