Answer:

Step-by-step explanation:

12x - 3 = 180 - (7x - 26) supplementary angles

19x = 209

x = 11

m∠DEC = 12(11) - 3 = 129°

m∠BCE = 7(11) - 26 = 51°

M∠ADE = 129 - 72 = 57° exterior angle rule

m∠EDB = 180 - 57 = 123° supplementary angles

m∠DBC = 57° corresponding angle to ADE

Remember P.E.M.D.A.S

57 - 12 ÷ 4 · 3

= 57 - 3 · 3

= 57 - 9

= 48

Answer:

This equation is equivalent to $20x-22$

$\mathrm{Expand}\:3\left(2x-5\right):\quad 6x-15\\=14x-7+6x-15\\\mathrm{Simplify}\:14x-7+6x-15:\quad 20x-22\\=20x-22$
