Förenkla uttrycket. \( \begin{array}{ll}3 \text { a) } 6 x-5+x+4 & \text { b) } 1+3 x+2-5 x \\ 4 \text { a) } 7+3(2-3 x) & \text { b) } 9-2(x+1)\end{array} \)

Simplify the expression by following steps: - step0: Solution: \(7+3\left(2-3x\right)\) - step1: Expand the expression: \(7+6-9x\) - step2: Add the numbers: \(13-9x\) Calculate or simplify the expression \( 1+3*x+2-5*x \). Simplify the expression by following steps: - step0: Solution: \(1+3x+2-5x\) - step1: Add the numbers: \(3-2x\) Calculate or simplify the expression \( 9-2*(x+1) \). Simplify the expression by following steps: - step0: Solution: \(9-2\left(x+1\right)\) - step1: Expand the expression: \(9-2x-2\) - step2: Subtract the numbers: \(7-2x\) Calculate or simplify the expression \( 6*x-5+x+4 \). Simplify the expression by following steps: - step0: Solution: \(6x-5+x+4\) - step1: Add the terms: \(7x-1\) Här är de förenklade uttrycken: a) \( 6x - 5 + x + 4 = 7x - 1 \) b) \( 1 + 3x + 2 - 5x = 3 - 2x \) c) \( 7 + 3(2 - 3x) = 13 - 9x \) d) \( 9 - 2(x + 1) = 7 - 2x \) Om du har fler frågor eller behöver ytterligare hjälp, tveka inte att fråga!
