(6 • 3 - 2x +3) - (-3 • 3 + 5 • 2 + 4x - 7)
first lorne added all binomials
(21 - 2x) - (-6 + 4x)
then took away the parentheses
21 - 2x + 6 + 4x
added them again o_o
27 + 2x
and ended up you her answer, shown above
GCF of 12,18 = 6
LCM of 12,18 = 36
1.3 so closer to 1 !! Best of luck
Answer:
a. No
b. Yes
c. No
d. Yes
e. Yes
Step-by-step explanation:
a. 8 + 13 = 21. No
b. -6 - 10 = -4. Yes
c. 6 × 4.6 = 27.6. No
d. 15 × 3.9 = 58.5. Yes
e. -6 × (-5) = 30. Yes
To find y, divide the first equation by 2.
y = 4
To find x, use that value for y in the second equation. Add 4, then divide by 2.
15·4 = 2x -4
60 +4 = 2x
64/2 = x = 32
The solution is (x, y) = (32, 4).
