\frac { 49} { 15x } = \frac { 11} { 3x } - \frac { 2} { 15}4915x=113x215

15x[\frac { 49} { 15x } = \frac { 11} { 3x } - \frac { 2} { 15}]15x[4915x=113x215]

49 = 5*11-2*x49=5112x

Add 2/15215

49/[15x]+2/15=11/[3x]4915x+215=113x

Subtract 49/[15x]4915x

2/15=11/[3x]-49/[15x]215=113x4915x

2/15=55/[15x]-49/[15x]215=5515x4915x

2/15=6/[15x]215=615x

Cross multiply

15x xx 2 = 16 xx 615x×2=16×6

30x=9630x=96

divide by 30

x=96/30=32/10=3.2x=9630=3210=3.2
