Gnoma [55]

Answer: -2x+7y+16

Step-by-step explanation:

1. Distribute 2 through the parentheses

  • 4x+6y+3(5-2x)+1+y              
  • 4x+6y+15-6x+1+y

2. Collect like terms

  • -2x+6y+15+1+y  
  • -2x+7y+15+1
  • -2x+7y+16

3. Solution, -2x+7y+16

Can someone tell me the answer and show me how to find it?
kiruha [24]

Answer:

The value of x is 20°

Step-by-step explanation:

Given that angle in a straight line is 180°. Then you can find the value of x:

55° + (6x+5)° = 180°

55° + 6x + 5° = 180

6x + 60° = 180°

6x = 180 - 60

6x = 120°

x = 20°
