Answer:
x=-17/19, y=131/19. (-17/19, 131/19).
Step-by-step explanation:
-19x=26-9
-19x=17
x=-17/19
9(-17/19)=54-9y
-153/19=54-9y
9y=54-(-153/19)
9y=54+153/19
9y=1026/19+153/19
9y=1179/19
y=(1179/19)/9
y=(1179/19)(1/9)
y=1179/171
y=131/19
F(x) = (-3)2 - 5(-3) + q
= -6 + 15 + q
= 9 + q
Subtract the two equations to eliminate g :
(3g + h) - (3g - 2h) = (5 1/5) - (-6 4/5)
3h = (5 1/5) + (6 4/5)
Write the mixed numbers as improper fractions with a common denominator and solve for h :
3h = (25/5 + 1/5) + (30/5 + 4/5)
3h = 26/5 + 34/5
3h = 60/5
3h = 12
h = 12/3
h = 4
Solve for g :
3g + h = 5 1/5
3g + 4 = 5 1/5
3g + 4 = 26/5
3g = 26/5 - 4
3g = 26/5 - 20/5
3g = 6/5
g = (6/5)/3
g = 2/5
