Question
Solve each equation, and check the solution. If applicable, tell whether the equation is an identity or a contradiction. $-2 x+5 x-9=3(x-4)-5$
Step 1
On the left side, combine like terms $-2x$ and $5x$ to get $3x$. On the right side, distribute $3$ to $(x-4)$ and then subtract $5$ to get $3x - 12 - 5$. So, the equation becomes: \[3x - 9 = 3x - 17\] Show more…
