4x+3=2x-5 solve the equation
Answers
Solution:
EQUALS,
(This step tells that we have changed 2x into the Left hand side and +3 into the Left Hand Side. And due to changing the places, they have changed their values. +3 is changed into -3 and +2x is changed into -2x)
EQUALS,
(Due to Subtraction of 4x and 2x, we have got 2x. And in addition of -5 and -3 we have got -8)
EQUALS,
(In this above step, we have changed the space of 2 into the Right Hand Side. It's work is now to divide it with -8)
EQUALS,
(In this above step, we have divided -8 with 2 and getting the result -4)
Therefore, the value of x is -4.
Answer:
x = -4
Step-by-step explanation:
First Method: By transposing
Given,
4x + 3 = 2x - 5
Step 1: Transpose 2x to LHS and 3 to RHS
4x - 2x = -5 - 3 = -8
Step 2; Subtract 2x from 4x
2x = -8
Step 3: Transpose 2 to RHS
x = -8/2
x = -4
Second Method: By adding, subtracting, multiplying or dividing LHS and RHS by same numbers.
Given,
4x + 3 = 2x - 5
Step 1: Subtract 2x from both sides
4x - 2x + 3 = 2x - 2x - 5
or 2x + 3 = -5
Step 2: Subtract 3 from both sides
2x + 3 - 3 = -5 - 3
or 2x = -8
Step 3 : Dividing both sides by 2
x = -8/2
x = -4
