    Answer:

    a. x=5.25

    b. x=-0.33

    Step-by-step explanation:

    You need to solve for the variable “x” in each equation. Then:

    a. You need to add 5 to both sides of the equation:

    4x - 5 +(5)= 16+(5)\\\\4x= 21

    Now you need to divide both sides of the equation by 4, getting:

    \frac{4x}{4}=\frac{21}{4}\\\\x=5.25

    b. You need to subtract 35 from both sides of the equation:

    35 + 3x - 11-(35)= 23-(35)\\\\3x-11=-12

    Add 11 to both sides:

    3x-11+(11)=-12+(11)\\\\3x=-1

    Now you need to divide both sides of the equation by 3, getting:

    \frac{3x}{3}=\frac{-1}{3}\\\\x=-0.33

    Answer:

    a: 5.25 b: -0.33

    Step-by-step explanation:

    a:

    4x – 5 = 16

    isolate the variable. this is done by putting only the variable on the left side and the numbers on the right side. when moving the 5 to the right side, it is counted as a -5 because of the minus in front. when moving it, be sure to change from – to + and vice versa.

    4x = 16 + 5

    4x = 21

    x = 21/4

    x = 5.25

    b:

    same process

    35 + 3x – 11 = 23

    move the 35 to the right, changing it to a -35

    3x – 11 = 23 – 35

    move the -11

    3x = 23 – 35 + 11

    3x = -12 + 11

    3x = -1

    x = -1/3

    x = -0.33
