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
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
