Solving 3(x+2)+4=4(2x1)+93(x + 2) + 4 = 4(2x - 1) + 9

To solve the linear equation 3(x+2)+4=4(2x1)+93(x + 2) + 4 = 4(2x - 1) + 9, begin by using the distributive property to eliminate the parentheses on both sides. This expands the equation to 3x+6+4=8x4+93x + 6 + 4 = 8x - 4 + 9. Next, combine the constant like terms on each side to simplify the equation to 3x+10=8x+53x + 10 = 8x + 5. To collect the variable terms on one side, subtract 3x3x from both sides, yielding 10=5x+510 = 5x + 5. Then, subtract 55 from both sides to isolate the variable term, which results in 5=5x5 = 5x. Finally, divide both sides by 55 to find the solution, x=1x = 1. The solution can be verified by substituting 11 back into the original equation to confirm it produces a true statement.
