Question

Math hw plz help idk how to do it

Answer 1

Firstly, foil 4(7 - 2x): $40-5x=28-8x+5x$

Next, combine like terms: $40-5x=28-3x$

Next, add 5x on both sides of the equation: $40=28+2x$

Next, subtract 28 on both sides of the equation: $12=2x$

Lastly, divide both sides by 2 and your answer will be: $6=x$

Answer 2

40 - 5x = 4(7 - 2x) + 5x

First, distribute 4 to all terms within the parenthesis

4(7 - 2x) = 28 - 8x

40 - 5x = 28 - 8x + 5x

Combine like terms

40 - 5x = 28 (-8x + 5x)

40 - 5x = 28 - 3x

Isolate the x. Add 3x to both sides, and subtract 40 from both sides

40 (-40) - 5x (+3x) = 28 (-40) - 3x (+3x)

-5x + 3x = 28 - 40

-2x = -12

Divide -2 from both sides

-2x/-2 = -12/-2

x = -12/-2

x = 6

6 is your answer

hope this helps
