Answer:
One solution
Step-by-step explanation:
In a one- variable equation has infinitely many solutions when solving results in a true statement, such as 2=2
In a one- variable equation has one solution when solving results in one value for the variable, such as x = 5
In a one - variable equation has no solution when solving results in an untrue statement, such as 2=3
So, in this case the result x = -2 belongs to the 2nd sentence where it says one solution.
Hope this helps :)
(4x + 134) + (3x + 32) = 180
7x + 166 = 180
7x = 14
x = 2
(3x + 22) + (3x + 128) = 180
6x + 150 = 180
6x = 30
x = 5
The answer is D
