Answer:
x = 
Step-by-step explanation:
Given
5xy + a = c ( isolate 5xy by subtracting a from both sides )
5xy = c - a ( isolate x by dividing both sides by 5y )
x = 
Answer:
yes, they are parallel because their slopes are the same
Step-by-step explanation:
if you put each equation into slope-intercept form and compare slopes you can see whether they are parallel or not
2x + y = 14
y = -2x + 14
slope = -2
2y + 4x = 14
2y = -4x + 14
slope = -4/2, which simplifies to be -2
