Answer: x = 12
Step-by-step explanation:
1. add 5x + 1x which will equal 6x so now your equation is: 6x + 6 = 78
2. subtract 6 from 78 to get 72: 6x = 72
3. divide 72 by 6x to get your answer 12
There are two sides (heads and tails). So one head would be 1/2, and one tail would also be 1/2.
Answer:
x2−3x+2=x2−2x−x+2
x(x−2)−1(x−2)=(x−2)(x−1)
Now
x2−4x+3=x2−3x−x+3
x(x−3)−1(x−3)=(x−3)(x−1)
Thus, the only common factor is (x-1)
Option A
hiiiii
-2x=5 is the right answer
Answer: x = 2/7y + 3/7 and
x= -5/4y + 0.8125
Step-by-step explanation: Let's solve for x.
7x−2y=3
Step 1: Add 2y to both sides.
7x − 2y + 2y= 3 + 2y
7x = 2y + 3
Step 2: Divide both sides by 7.
7x/7 = 2y+3/7 this is for the second answer Step 1: Add -5y to both sides.
4x+5y+−5y=3.25+−5y
4x=−5y+3.25
Step 2: Divide both sides by
4/4 x 4 = −5y + 3.25/4
