I need geometry help? please?

Question

(5x+4) + (4x+1)= (45+x)

what is x?

Answer 1

(5x+4) + (4x+1)= (45+x)

5x + 4x + 4 + 1 = 45 + x

get all the "x-factors" on one side.

5x + 4x - x = 45 - 4 - 1

simplify:

8x = 40

divide by 8:

x = 5

Answer 2

Its algebra.

5x + 4 + 4x + 1 = 45 + x

9x + 5 = 45 + x

8x = 40

x = 5

Answer 3

First of all it is algebra,then 9x+5=45+x,8x=40,x=5

Answer 4

The () are irrelevant so just add it all up.

9x+5=45 +x

Subtract the x

8x+5=45

Subtract the 5

8x=40

Divide by 8

x=5

Answer 5

(5x+4)+(4x+1)=(45+x)

Regroup them to get:

(5x+4x)+(4+1)=(45+x)

9x+5=45+x

subtract x on both sides:

8x+5=45

subtract 5 on both sides:

8x=40

divide by 8 on both sides:

x=5

Therefore, x=5.

Answer 6

9x+5=45+x

8x=40

x=5

Answer 7

9x+5=x+45

subtract x from both sides

8x + 5 = 45

subtract 5 from both sides

8x = 40

divide both sides by 8

x=5
