Question

How many solutions will this system of equations have?

y = 3.5x - 3.5
y = -3.5x + 3.5

No solution

Infinite solutions

One solution

Two solutions

Answer 1

I'm giving medals

Answer 2

one solution..only because it is linear eq and each linear eq has a single solution..okay..??

Answer 3

perfect! thanks dude

Answer 4

rewrite to
y-3.5x = -3.5
y+3.5x = 3.5
solve top equation ---> x = y/3.5 +1
Substitute this into bottom equation:
y + 3.5(y/3.5 +1) = 3.5
Simplify
y + (y + 3.5) = 3.5
2y +3.5 = 3.5
2y = 0
y = 0
Substitute y = 0 in an equation to find x:
0 + 3.5x = 3.5
x = 1

It helps to know why
