Question

Find the values of x and y for which the lines are parallel.
a)x = 47, y = 79
b)x = 58, y = 57
c)x = 79, y = 49
d)x = 79, y = 47

Answer 1

well because the lines are parallel,
x-5 = 74
and 74+58+(y+1) = 180 ----> 133 + y = 180

so just solve for x and y now

Answer 2

74=x-5
x=74+5=79
74+58+y+1=180
133+y=180
y=180-133=47
