Question

Which of the following equations have the same solution? Solve all three equations separately and explain each step.

I. 2x + 4 = 3x – 11
II. 3x + 3 = 51
III. 2x+1/3=x+6/2

Answer 1

@KingGeorge help me on this one?

Answer 2

@surjithayer

Answer 3

Solve each for x.

Answer 4

2x+4=3x-11
-2x -2x
4=x-11
+11 +11
x=15 ?

Answer 5

3x + 3 = 51
-3 -3
3x= 48

x=16 ?

Answer 6

i solve III
\[\frac{2x+ 1 }{ 3 }=\frac{ x+6 }{ 2 }\]
cross multiply
4x+2=3x+18
4x-3x=18-2
x=16

Answer 15

Neveah has created the function f(x) = 2x +4/3 to represent the growth of her hair, where x represents the number of months since her last hair cut. Neveah discovers that using the inverse function to solve for x = 6, she can predict when her hair will have grown 6 inches. Explain to Neveah how to accomplish this, using complete sentences.
