No because you are distributing and for 3(x+11/2), you multiply 3 times x is 3x and then 3 times 11/2 is 16 1/2 . All together 3x+16 1/2 or 16.5
It is not equal to 3x+11/2.
25+14=39
R=25
Hope I helped
This has one solution because x can only equal 400
X equals 15!
so you subtract 2x minus x which gives you x. Then you get x equals 15!
Hope this helps!
