Set the two lines equal to each other
x^3+2x-1=2x+15
Isolate x
x^3=16
x=(16)^1/3 or x=5.33

nicely in case you have a 'Texas device TI-80 4' calculator then you certainly could in simple terms placed it interior the y= button then click graph.....or the slope often is the -2 and the y intercept +a million so get on the a million and flow down 2 suited a million=)

y=x^3+2x-1 and y=2x+15
x^3+2x-1=2x+15
x^3 = 16
x = 2*2^(1/3)
x = approximately 2.5198421
