= 2x + 11
Steps
(8x+9) -(6x-2)
Remove ( a ) = a
8x + 9 - 6x + 2
Simplify
8x+ 9 - 6x + 2: 2x + 11
= 2x + 11 <----- your answer
Please tell me if this was right
Answer:
4x + 7 = 3
Step-by-step explanation:
let the number be x
4 times x = 4x
sum of 4x and 7 = 4x + 7
Sum of 4x + 7 is 3 becomes;
4x + 7 = 3

Answer:
x = 5
Step-by-step explanation:
The total degrees in a 4 sided polygon is 360°
360° = 51° + 51° + 2(28x - 11°)
56x - 22° + 51° + 51° = 360°
56x = 280°
x = 5
