How do I solve 1/2 (x+4-21x-5) = 46

x=-91/1840

Step-by-step explanation:

Firstly deal with the bracket

2 (x+4-21x-5)

2 (x-21x+4-5)

2 (-20x-1)

-40x-2

Back to the question

1/-40x-2=46

Cross multiply

46 (-40x-2) = 1

-1840x-92=1

Add 92 to both sides

-1840x=91

Divide both sides by-1840

x=-91/1840

x=-4.65

Step-by-step explanation:

1/2 (x+4-21x-5) = 46

1/2 (-20x-1) = 46

1/2 (-20x) + 1/2 (-1) = 46

1/2 (-20x) -.5=46

1/2 (-20x) +.5=46

.5 (-20x) = 46.5/.5

-20x=93

x=-4.65
