68= 4x-2+30 (notice they are vertical angles)
68= 4x+28
40=4x
10=x
68+y= 180 (forms a straight angle)
y=112
Final answer: x=10, y=112
Step-by-step explanation:
{9x+3y=-36
y=-3x-21
9x-9x-36=-36
y=-3x-21
x=0
y=-21
Log(k + 2k) = log60 - log4
for two functions to be equal, the arguments of each must be equal
k = 5
