\(a,3\left(x-12\right)-2\left(2x-4\right)=3-2\left(x-11\right)\)
\(3x-36-4x+8=3-2x+22\)
\(3x-4x+2x=3+22+36-8\)
\(x=53\)
\(a,3\left(x-12\right)-2\left(2x-4\right)=3-2\left(x-11\right)\)
\(3x-36-4x+8=3-2x+22\)
\(3x-4x+2x=3+22+36-8\)
\(x=53\)
\(b,5\left(x-7\right)-4\left(x-8\right)=5-2\left(x-4\right)+2x\)
\(5x-35-4x+32=5-2x+8+2x\)
\(5x-4x+2x-2x=5+8+35-32\)
\(x=16\)
a, x =53 b,x= 16 k tui nha hinh nen ban de thuong qua
