    Kwa mazoezi yafuatayo, tatua usawa. Andika jibu lako la mwisho katika nukuu ya muda.

    60. \(5 x-8<12\)
    61. \(-2 x+5>x-7\)
    62. \(\frac{x-1}{3}+\frac{x+2}{5} \leq \frac{3}{5}\)
    63. \(|3 x+2|+1 \leq 9\)
    64. \(|5 x-1|>14\)
    65. \(|x-3|<-4\)

    Kwa mazoezi yafuatayo, tatua usawa wa kiwanja. Andika jibu lako katika notation ya muda.

    66. \(-4<3 x+2 \leq 18\)
    67. \(3 y<1-2 y<5+y\)

    Kwa mazoezi yafuatayo, grafu kama ilivyoelezwa.

    68. Graph thamani kamili kazi na grafu kazi ya mara kwa mara. Angalia pointi za makutano na kivuli\(x\) -axis anayewakilisha suluhisho lililowekwa kwa usawa. Onyesha grafu yako na uandike jibu lako la mwisho katika maelezo ya muda. \[|x+3| \geq 5\nonumber\]
    69. Grafu mistari yote ya moja kwa moja (upande wa kushoto kuwa\(y^{-1}\) na upande wa kulia kuwa y2) kwenye shaba sawa. Pata hatua ya makutano na kutatua usawa kwa kuchunguza ambapo ni kweli kulinganisha\(y\) maadili ya mistari. Angalia muda ambapo usawa ni kweli. \[x+3<3 x-4\nonumber\]
