17x = 85
x = 85/17
x = 5.
Hence x = 5 makes above equality true.

5 people wanted to use flour for cooking. Altogether, they had 4kg of flour. They wanted to split the four into 5 equal amounts. How many kg of flour did each person get?
Hope this helps!
-21 - 7x = 8x + 24
add 21 to both sides
-7x= 8x + 45
subtract 8x from both sides
-15x= 45
divide both sides by -15
x= -3
Hope this helps! :)
Answer:
x=132°
Step-by-step explanation:
All four angles should add up to 360°
65°+86°+77°+x=360°
x=132°
Answer:
a = 26
Step-by-step explanation:
Solve for a:
22 = a - 4
Hint: | Reverse the equality in 22 = a - 4 in order to isolate a to the left-hand side.
22 = a - 4 is equivalent to a - 4 = 22:
a - 4 = 22
Hint: | Isolate terms with a to the left-hand side.
Add 4 to both sides:
a + (4 - 4) = 4 + 22
Hint: | Look for the difference of two identical terms.
4 - 4 = 0:
a = 22 + 4
Hint: | Evaluate 22 + 4.
22 + 4 = 26:
Answer: a = 26
