The solution is x = 3
Further explanation:
Assuming the given equation is:
-3(x+4)+15=6-4x
First of all, -3 will be distributed to (x+4)
So,
[tex]-3x-12+15 = 6-4x[/tex]
Simplifying
[tex]-3x +3 = 6-4x[/tex]
In order to solve the equation we have to isolate x on one side of the equation
[tex]-3x + 4x = 6-3\\x = 3[/tex]
so, the solution is x=3
Verification:
Putting x= 3 in equation:
[tex]-3(3+4)+15 = 6-4(3)\\-3(7)+15 = 6-12\\-21+15 = -6\\-6=-6[/tex]
