Answer:
x=5
Step-by-step explanation:
3x+7-x+6=23
3x-x=23-6-7
3x-x=23-13
3x-x=10
2x=10
x=5

Answer:
-3e^-2x(x+1)
Step-by-step explanation:
formula of byparts integration:
g(x)∫f(x)dx-∫∫f(x).d/dx(g(x))dx
=(6x+3)∫e^-2x dx-∫∫e^-2x.d/dx(6x+3)dx
=(6x+3)((e-2x)/-2)-∫(e^-2x)/-2 .6 dx
=(6x+3)((e-2x)/-2)+3(e^-2x)/-2
=(6xe-2x+3e-2x+3e-2x)/-2
=(6xe-2x+6e-2x)/-2
=6e^-2x(x+1)/-2
=-3e^-2x(x+1)
