Graphical? I don't think it should be required...the question doesn't ask for it to be done graphically

3x= 4 sin x.
You can draw y = 3x and y= 4 sin x.
In case don't find any other way, you can try it.
Sign change method...?

x 3x-sinx
1 -0.37
1.05 -0.32
1.1 -0.26
1.15 -0.2
1.2 -0.13
1.25 -0.05
1.3 0.05
1.35 0.15
1.4 0.26
1.45 0.38
1.5 0.51
1.55 0.65
sign change between x=1.2 and 1,43 rads x=1.25 is too small sox=1.3 to 1 dp
