-2x-3.(x-17)=34-2(-x+25)
-2x-3x+51=34+2x-50
-2x-3x+51-34-2x+50=0
-7x+67=0
-7x=-67
x=\(\frac{67}{7}\)
- 2x - 3( x- 17) = 34 - 2( -x + 25)
- 2x - 3x + 51 = 34 + 2x - 50
- 2x - 3x - 2x = - 51 + 34 - 50
-7x = -67
x = \(\frac{67}{7}\)
Vậy x =\(\frac{67}{7}\)
\(-2x-3\left(x-17\right)=34-2\left(-x+25\right)\)
\(\Leftrightarrow-2x-3x+51=34+2x-50\)
\(\Leftrightarrow-5x+51=-16+2x\)
\(\Leftrightarrow-7x=-67\Leftrightarrow x=\frac{67}{7}\)
