Answer:
32
Step-by-step explanation:
32 X 2 = 64. 64 - 9 = 55.
Answer:
Given the equation: 4(2x-1)+5 = 3+2(x+1) .....[1]
Distributive property states that when a number is multiplied by the sum of two numbers, then the first number can be distributed to both of those numbers and multiplied by each of them separately.
i.e,
Applying distributive property, in [1]we get;
Simplify:
.....[2]
Like terms are those terms that have the same variables and powers
Combine like terms on each side in equation [2];
8x +(-4+5) = (3+2) +2x
Simplify:
8x + 1 =5 + 2x
The terms which Carey combine are; -4 +5 and 3 + 2
1/2. 1/6
1/2×3=3/6
3/6+1/6=4/6
4/6=2/3
2/3
Answerwhats the question
Step-by-step explanation:
Here are two ways to solve
Method 1: Elimination
x+y = 3k ... start with the first equation
4x+4y = 12k ... multiply every term by 4
4x-6k = 2y ... move onto the second equation
4x-2y = 6k ... subtract 2y from both sides and add 6k to both sides
The system of equations turns into
4x+4y = 12k
4x-2y = 6k
which, when subtracted, leads to 0x+6y = 6k so y = k when you divide both sides by 6
Use y = k to find x
x+y = 3k
x+k = 3k
x = 2k
The answer is 2k
=========================================================================================
Method 2: Substitution
x+y = 3k ... start with the first equation
y = -x+3k ... isolate y; subtract x from both sides
4x-6k = 2y ... move onto the second equation
4x-6k = 2(-x+3k) ... plug in y = -x+3k; solve for x
4x-6k = -2x+6k
4x+2x = 6k+6k
6x = 12k
x = 12k/6
x = 2k
=========================================================================================
Whichever method you use, the answer is x = 2k
