Math Problem Statement

1.Solve the equation for all values of x. open vertical bar, 4, x, minus, 1, close vertical bar, plus, 6, equals, 3, x ∣4x−1∣+6= 3x

Solution

We are given the equation:
4x1+6=3x|4x - 1| + 6 = 3x

Step 1: Isolate the absolute value expression

Subtract 6 from both sides: 4x1=3x6|4x - 1| = 3x - 6

Step 2: Solve for two cases

Since 4x1|4x - 1| represents two possible values (the expression inside the absolute value can be positive or negative), we solve for two cases:

Case 1: Positive case

4x1=3x64x - 1 = 3x - 6 Subtract 3x3x from both sides: x1=6x - 1 = -6 Add 1 to both sides: x=5x = -5

Case 2: Negative case

4x1=(3x6)4x - 1 = -(3x - 6) Distribute the negative sign: 4x1=3x+64x - 1 = -3x + 6 Add 3x3x to both sides: 7x1=67x - 1 = 6 Add 1 to both sides: 7x=77x = 7 Divide by 7: x=1x = 1

Step 3: Check both solutions

We need to check if both values satisfy the original equation.

For x=5x = -5: 4(5)1+6=3(5)|4(-5) - 1| + 6 = 3(-5) 201+6=15|-20 - 1| + 6 = -15 21+6=15| -21 | + 6 = -15 21+61521 + 6 \neq -15 So, x=5x = -5 is not a solution.

For x=1x = 1: 4(1)1+6=3(1)|4(1) - 1| + 6 = 3(1) 41+6=3|4 - 1| + 6 = 3 3+6=3|3| + 6 = 3 3+633 + 6 \neq 3 This doesn't satisfy either, so there is no solution to this equation.

Conclusion:

There is no solution to this equation.
