    Start by combining like terms, like the -5 and -4, and the 160 and -17

    Oh wait, you made a mistake when you subtracted the 17, it should have been 143

    Then add nine to both sides, and divide by two, and you should have your answer

    So back to the beginning. 2(2x-5-4)=160-17

    You can reduce this to 2(2x-9)=143

    So, without having to distribute the 2, since its already on the outside, you can just divide both sides by 2

    Now you can add nine to both sides to get the x term by itself

    \[2\left(2x-5-4\right)=160-17\quad :\quad x=\frac{161}{4}\quad \left(\mathrm{Decimal:\quad }x=40.25\right)\]

    Yes, after you add the nine, divide both sides by 2 to get your final answer, 40.25

    What is the solution to the following equation? 2(3x − 7) + 18 = 10 1 3 5 6

    \[2\left(3x-7\right)+18=10\quad :\quad x=1\] 2(3x − 7) + 18 = 10 6x-14+18=10 6x+4=10 subtract 4 on both sides 6x-4+4=10-4 6x=6 x=1

    just take every terms without x to the right side of equation to get the value of x it's simple first try your own then ask for explanation that's the way of learning.
