Solve the equation 5x + 3 = 2 (x-1) -4
Answers
Step-by-step explanation:
5x + 3 = 2(x-1)-4
5x + 3 = 2x -2-4
5x + 3 = 2x - (-4)
5x +3x = (-4) -3
7x =(-7)
x= 7/ (-7)
x = -1
Answer:
Solve this equation 5x−1=3x+5 by separating the variable terms on one side of the equation and the constant term on another side.
We use the addition-subtraction property to transform a given equation to an equivalent equation of the form x = a.
First, add 1 to each side of the equation and then subtract 3x from each side of the equation.
Complete step-by-step answer:
We have to solve the equation 5x−1=3x+5.
Basically, we have to find the value of x .
Use the addition-subtraction property to transform a given equation to an equivalent equation of the form x = a
Add 1 to the each side of the equation,
5x−1+1=3x+5+1
⇒5x=3x+6
Subtract 3x from each side of the equation.
5x−3x=3x+6−3x
⇒5x−3x=6
⇒2x=6
Divide 2 to each side of the equation.
⇒2x2=62
⇒x=3
Final Answer: The solution of the equation 5x−1=3x+5is x=3.
Note:
Substitute x=3 into the equation the right-hand side of equation,
5(3)−1=15−1
5(3)−1=14
Substitute x=3 into the equation the left-hand side of equation,
3x+5=3(3)+5
3x+5=14
Since L.H.S. = R.H.S.
The solution of the equation is x=3.
