how many solutions does this equation have

Question

y=-5x-7 and 10x-2y=14

Answer 1

the equations y = -5x - 7 and

10x - 2y =14 or 2y = 10x - 14 or y = 5x - 7

So , the 2 equations are

y = -5x - 7

and y = 5x - 7

Solving, we have

2y = -14 or y = -7

and x = 0

So, there is a unique solution

for x & y
