Answer:
Options: A, B, and C correctly solve for x.
Step-by-step explanation:
A).
= 
Multiplying both sides by 2 gives;
5x = 15
x = 15 ÷ 5 = 3
∴ This option correctly solve for x.
B).
x +
= 7
x = 7 -
= 
∴ This option correctly solve for x.
C).
x + 3 = 
x = 
But the option give x as 5/6 hence this option does not correctly solve for x.
D).
5x = 11/2
x = 11/2 ÷ 5 = 11/2 × 1/5 = 11/10
But the option gives x as 10/11 so it does not correctly solve for x.
Answer:
288 and 289 are the two pages.
Step-by-step explanation:
The answer is -3 and 4. (-3)•4=-12 and -3+4=1
Answer:
The answer is y = 2x - 3.
Step-by-step explanation:
Move 2x to the right side of the equation by adding it to both sides:
-2x + y + 3 = 0
<u>+ 2x + 2x</u>
y + 3 = 2x
Then, move 3 to the right side of the equation by subtracting it form both sides:
y + 3 = 2x
<u> - 3 - 3</u>
y = 2x - 3
