Solve the equation `3x-7=3(x+1)`
`3x-7=3x+3` Distribultive property
`3x=3x+10` Add 7 to both sides
`0=10` Subtract `3x` from both sides
Since `0!=10` for any `x` , there is no solution.
** You might see this as trying to find the intersection of the lines:
`y=3x-7` and `y=3(x+1)` . Setting the right hand sides equal gives where the y values are the same. But these lines are parallel; both have slope of 3 but different y-intercepts. Being parallel, they never intersect so there is no solution. **
impossible no solution
when u solve right side
it is 3X+3. right??? 3(X+1) -> 3*X+3*1
so, right side 3x is equal to left side 3x
after this,,, -7should be equal as 3.... it doesnt make sense...
this problem has no solution...
