I tried to solve this problem but I can't seem to get v-(4-v)=-2(2v-1)?

    v-(4-v)=-2(2v-1)

    v-4+v=-4v+2

    2v-4=-4v+2

    2v+4v=2+4

    6v=6

    v=1 answer

    checking

    1-(4-1)=-2(2(1)-1)

    1-3=-2(2-1)

    -2=-2 check

    Okay, easy! Just get a piece of paper. Now, write down the equation: v-(4-v)=-2(2v-1). Then, multiply the -2(2v-1) so that is -4v+2 so now the equation is: v - 4 + v = -4v + 2, subtract a v from each side, so now it is: -4-v=-5v+2 then, add a v to each side so the v's cancel out on the left and it becomes -4v on the right, the equation is now: -4=-4v+2. then subtract 2 from each side, and u get -6=-4v divide by -4 on each side, so you get 1=v

    And that should be the answer!

    :) Hope i helped!

    v-4v+v=-4v+2 (this is the first step when you get all the stuff out of ( )

    2v-4=-4v+2 (adding and combining terms)

    6v=6 (bringing terms to the correct sides of equation)

    v=1

    Hope that helps!

    I take the question as v-(4-v)=-2(2v-1)

    Open brackets to get v-4+v = -4v+2

    Group like terms to get v+v+4v = 2+4

    Simplify to get 6v = 6

    and hence v = 1.

    v-(4-v)=-2(2v-1)

    v - 4 + v = -4v + 2

    2v + 4v = 2 + 4

    6v = 6

    v = 1

    -4+2v=-4v+2

    v=1

    v - (4-v) = -2(2v-1)

    v - 4 + v = -4v + 2

    2v -4 = -4v + 2

    6v = 6

    v = 1.

    v-(4-v)=-2(2v-1)

    v-4+v = -4v +2

    2v-4 = -4v+2

    2v+4v = 2+4

    6v = 6

    v= 1

    v - 4 + v = -4v + 2

    2v - 4 = -4v + 2

    6v = 6

    v = 1
