A) -9 -7(x+9)=9(x-5)-14x -7x-63=9x-45-14x -45 -45 -7x-18=9x-14x +7x +7x -18=9x+7x-14x -18=2x (-18)/2=(2x)/2 -9=x
-7(x + 9) = 9(x - 5) - 14x → Given -7x - 63 = 9x - 45 - 14x → Distributive Property -7x - 63 = -5x - 45 → Combine like terms (9x and -14x) -12x - 63 = -45 → Addition property of equality (-7x and -5x) -12x = 18 → Addition property of equality (Add 63 to both sides) x = -³/₂ or -1 ¹/₂ or -1.5 Hope it helps.

Answer:
Step-by-step explanation:
Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
Therefore
Angle A =67 degrees
Angle B= 94 degrees
Angle C = 19 degrees
