Answer:
one solution
Step-by-step explanation:
2(2b-4)+5=7+2b
4b - 8 + 5 = 7 + 2b
4b -3 = 7 + 2b
4b - 2b = 7 + 3
2b = 10
b = 10/2
b = 5.
it can have only 5 as solution that will be only one solution if we change the value of 5 to other number then the answer will be wrong
x=58 degrees
The angle is a right angle (90 degrees)
90-32=58
j + 47 = 53
x and y = 66.5
180-47=133
133/2=66.5
