Assoli18 [71]

Answer:

• First assign any label to the equations:

${ \tt{2x + 3y = 10 - - - \{eqution \: (a) \}}} \\ { \tt{ - 6x - 9y = 30 - - - \{equation \: (b) \}}} \\$

• Multiply equation (a) by 3

$\dashrightarrow \: { \tt{3 \times (2x + 3y = 10)}} \\ \dashrightarrow \: { \tt{6x + 9y = 30}}$

• Sum up the result with equation (b)

${ \underline{ + { \tt{ \binom{6x + 9y = 30}{ - 6x - 9y = 30} }}}} \\ { \tt{0x + 0y = 60}}$

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

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

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

$=c^5d^2$
