Question

What is the value of x in the equation 2(5x + 4) = 17?

A 5/2
B 2/5
C 9/10
D 17/18

Answer 1

`(9)/(10)`

Explanation:

`2(5x+4)=17,\\10x+8=17,\\10x=9,\\x=(9)/(10)`

Analysis:

2(5x+4)=17

• Distribute

10x+8=17,

• Subtract 8 from both sides to isolate x

10x=9

• Divide both sides by 10 to isolate x

x=9/10 (ans)

Answer 2

x = 9/10

Explanation:

2(5x + 4) = 17

Distribute

10x+8 =17

Subtract 8 from each side

10x +8-8 = 17-8

10x = 9

Divide by 10

10x/10 = 9/10

x = 9/10
