Q. Solve the equation for all values of x x .\newline4x+7=3x |4 x+7|=3 x \newlineAnswer: x= x=
  1. Understand absolute value equation: Understand the absolute value equation |\(4x+77|=33x").\newlineThe absolute value of a number is its distance from zero on the number line, regardless of direction. Therefore, |\(4x+77|") can be either \(4x+77") or -(\(4x+77)") depending on the value of x").
  2. Set up two equations: Set up two separate equations to solve for \(x, one for each case of the absolute value.\newlineCase 11: 4x+7=3x4x + 7 = 3x\newlineCase 22: (4x+7)=3x-\left(4x + 7\right) = 3x
  3. Solve first case: Solve the first case 4x+7=3x4x + 7 = 3x.
    Subtract 3x3x from both sides to isolate xx.
    4x+73x=3x3x4x + 7 - 3x = 3x - 3x
    x+7=0x + 7 = 0
    Subtract 77 from both sides to solve for xx.
    x=7x = -7
  4. Solve second case: Solve the second case (4x+7)=3x- (4x + 7) = 3x. First, distribute the negative sign inside the parentheses. 4x7=3x-4x - 7 = 3x Add 4x4x to both sides to get all xx terms on one side. 4x7+4x=3x+4x-4x - 7 + 4x = 3x + 4x 7=7x-7 = 7x Divide both sides by 77 to solve for xx. x=7/7x = -7 / 7 x=1x = -1
  5. Check first solution: Check both solutions in the original equation to ensure they are valid.\newlineFor x=7x = -7:\newline4(7)+7=3(7)|4(-7) + 7| = 3(-7)\newline28+7=21|-28 + 7| = -21\newline21=21|-21| = -21\newline212121 \neq -21, so x=7x = -7 is not a solution.
  6. Check second solution: Check the second solution x=1x = -1 in the original equation.\newline4(1)+7=3(1)|4(-1) + 7| = 3(-1)\newline4+7=3|-4 + 7| = -3\newline3=3|3| = -3\newline333 \neq -3, so x=1x = -1 is not a solution either.
  7. Conclude no solutions: Since neither of the found values for xx satisfy the original equation, we conclude that there are no solutions to the equation 4x+7=3x|4x+7|=3x.
