Answer:

x=2,y=5

Step-by-step explanation:

y=8x-11 ----(1)

y=-7x+19----(2)

Replace (1) in (2)

8x-11 =-7x+19

8x+7x=19+11

15x =30

x =30÷2

x =2

If x=2,then replace x=2 in (1)

y=8(2)-11

y=16-11

y=5

Answer:

#5: d=22, #6: $m=4\frac1{10}$ , #7: $2\frac3{11}=z$

Step-by-step explanation:

#5:

$2\cdot (4\cdot5-3^2)=2\cdot (4\cdot5-3\cdot3)=2\cdot (20-9)=2\cdot11=22$

#6:

$5\frac25-1\frac3{10}=5\frac4{10}-1\frac3{10}=4\frac1{10}$

#7:

$\frac{40-15}{5+6}=\frac{25}{11}=2\frac3{11}$
