Answer:</h2>
The number of solutions of the equation is:
One.
<h2>
Step-by-step explanation:</h2>
We are asked to find the number of solutions of the equation:
3x+6= -1-3+4x
(
<em>We know that a expression has a unique or one solution if it gives a single value of x after solving the expression.</em>
<em>and we obtain a no solution when the equation gives a false result i.e. the left and right hand side of equality are different.</em>
<em>and infinite many solution if the left and right hand side of equality is same but we can't get a fix value of x )</em>
Now on solving the expression we have:
3x+6= -4+4x
i.e. 4x-3x=6+4
i.e. x=10
Hence, we get a unique value of x.
Hence, the equation has one solution.
