One solution

Step-by-step explanation:

Hi,

3(x + 5) = -4x + 8

3x + 15 = -4x + 8

7x + 15 = 8

7x = -7

x = -1

One solution :)

exactly one solution

Step-by-step explanation:

3x+15=_4x+8

7x=8 -15

x=_7/7

x=-1

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
