Step-by-step explanation:

X=e+r/d

swap both sides

e+r/d=x

subtract e from both sides

e-e+r/d=x-e

r/d=x-e

multiply d to both sides

d×r/d=x-e×d

r=x-e×d

Alenkinab [10]

18) $19m^8n^8-\left(4m^5n\right)\left(3m^3n^7\right)$

$=19m^8n^8-4m^5n\cdot \:3m^3n^7$

$=19m^8n^8-12m^8n^8$

$=7m^8n^8$

19) $\left(-5cd\right)\left(-3c^4d\right)-\left(7c^2d^2\right)\left(2c^3\right)$

$=5cd\cdot \:3c^4d-7c^2d^2\cdot \:2c^3$

$=15c^5d^2-14c^5d^2$

$=c^5d^2$
