Question

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

Answer 1

Answer:

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

Answer 2

Answer:

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
