Step-by-step explanation:
Answer:
y = 3
Step-by-step explanation:
-7 = -4y + 5
Subtract 5 from both sides to isolate variable y:
-7 - 5 = -4y + 5 - 5
-12 = -4y + 0
-12 = -4y
Divide both sides by -4 to isolate variable y:
-12 ÷ -4 = -4y ÷ -4
(Negative ÷ Negative = Positive)
3 = 1y
3 = y
Check your work:
-7 = -4(3) + 5
Use PEMDAS:
-7 = -12 + 5
-7 = -7
Correct!

Answer:
x = 17.2
Step-by-step explanation:
since they are supplementary, when you add then together they equal 180
4x + 8 + 6x = 180
Combine like terms
10x + 8 = 180
subtract 8 from both sides
10x = 172
divide each side by 10
x = 17.2
hope this helps :)
