Answer:
x = -27
Step-by-step explanation:
5(x - 1) = 4(x - 8)
Distributive property
5x - 5 = 4x - 32
Subtract 4x from both sides
x - 5 = -32
Add 5 to both sides
x = -27

Answer:
7
Step-by-step explanation:
15+-8=7
So a complementary angle is going to equal 90 degrees.
The equation is : x - 10 + 4x - 10 = 90
Then, add together the matching terms : 5x - 20 = 90
Add 20 to both sides : 5x = 110
Then divide both sides by 5 : x = 22
Insert the value 22 into the first equation : (22 - 10) + (4*22 - 10) = 90
Solve : 12 + 78 = 90
Angle UVW = 12 and angle XYZ = 78
