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

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
