0.45m-9=0.9m

0.45 m - 9 = 0.9 m

m = - 20

Solution steps

0.45 m - 9 = 0.9 m

Multiply both sides by

100

45 m - 900 = 90 m

Move

900

to the right side

45 m = 90 m + 900

Move

90 m

to the left side

- 45 m = 900

Divide both sides by

- 45

m = - 20

- - 32

(\frac{7}{8})^{2}

m^{2} - 18 m + 81

∣ 1 - 6 x ∣ - 9 < - 6

y, x^{2} + y^{2} - 6 x - 4 y + 13 = 0
