Answer:
The answer is 4u-14.
Have a great rest of your day!
Answer: If u divide both sides by 3 you get the value o x 2 answer: Combine terms by transporting. The equation becomes 4x -7x = -21
Step-by-step explanation: 1. 4x=7(x-3) -----> Start with the given.
2. 4x=7x-21 -----> Distribute 7 by multiplying it to the individual terms inside the parenthesis. 7(x) - 7(3) = 7x -21
3. -3x=-21 ------> From step 2, combine like terms by transposing. The equation becomes 4x - 7x = -21. Simplifying, it becomes -3x = -21
4. x = 7 -----> Divide both sides by -3, you get the value o x.
Hope this helps :)
Answer: x = 4
y = - 3
Step-by-step explanation:
The given system of simultaneous equations is expressed as
x-3y = 13 ------------------------1
2x+4y=-4--------------------------2
We would apply the method of substitution in solving the equations. From equation 1, we would make x to stand alone by adding 3y to the left hand side and the right hand side of the equation. It becomes
x - 3y + 3y = 13 + 3y
x = 13 + 3y
Substituting x = 13 + 3y into equation 2, it becomes
2(13 + 3y) + 4y = - 4
26 + 6y + 4y = - 4
26 + 10y = - 4
Subtracting 26 from the left hand side and the right hand side of the equation, it becomes
26 - 26 + 10y = - 4 - 26
10y = - 30
Dividing the left hand side and the right hand side of the equation by 10, it becomes
10y/10 = - 30/10
y = - 3
Substituting y = - 3 into x = 13 + 3y, it becomes
x = 13 + 3 × - 3
x = 13 - 9
x = 4

Mutliplying decimals with numbers
Lets do the following multiplication
25
x419
9x25 = 2 2 5
1 x 25 = 2 5 0
4 X25 = 100 0 0 ...... add colums from top to bottom
= 1 0 4 7 5
for a decimal , just add a dot . or comma after 104 , this will be 104.75
so 25 x 4.19 = 104.75
