Answer:
if two angles r equal or sides r proportional
False I think it doesn't add up to 18
First solve for x in the first equation
x + 7y = 0
x = -7y
since x = -7y we can substitute -7y into the other equation wherever there is an x
2x - 8y = 22
2(-7y) - 8y = 22
-14y - 8y = 22
-22y = 22
y = -1
Now let's substitute -1 back into either of the original equations so we can solve for x
x + 7y = 0
x + 7(-1) = 0
x - 7 = 0
x = 7
So your solution set is
(7, -1)
Answer:
x = 0.5
Step-by-step explanation:
First, distribute -4 to the parentheses:
-14 = -4(9x - 1)
-14 = -36x + 4
Subtract 4 from both sides:
-18 = -36x
Divide each side by -36
0.5 = x
x = 0.5
