Solve and check the following linear equation. 6x-(4x-4)=14
1 answer:
<span>6x-(4x-4)=14
</span>
We have to <span>unfold the brackets and change the sign of each term.
</span><span>
</span><span>6x - 4x + 4 = 14
</span><span>
</span><span>2x + 4 = 14 | - 4
</span><span>
</span><span>2x + 4 - 4 = 14 - 4
</span><span>
</span><span>2x = 10 | :2
</span><span>
</span><span>2x:2 = 10:2
</span><span>
</span><span>x = 5
</span><span>
</span><span>
</span><span>Verification : 6*5 -(4*5 - 4) = 14
</span><span>
</span><span> 30 - 20 + 4 = 14
</span><span>
</span><span> 10 + 4 = 14
</span><span>
</span><span> 14 = 14 - true
