Question

5(3x+5)-4(2x-3)=5x+3(2x+12)+1

Answer 1

\(5(3x+5)-4(2x-3)=5x+3(2x+12)+1\)

\(\Leftrightarrow15x+25-8x+12=5x+6x+36+1\)

\(\Leftrightarrow15x+25-8x+12-5x-6x-36-1=0\)

\(\Leftrightarrow-4x=0\)

\(\Leftrightarrow x=0\)

Answer 2

Ta có:

\(5\left(3x+5\right)-4\left(2x-3\right)=5x+3\left(2x+12\right)+1\\ 15x+25-8x+12=5x+6x+36+1\\ 7x+37=11x+37\\ 7x=11x\\ x=0\)

Vậy x = 0
