How many solutions for each system
1 answer:
Infinitely many is the first one, because you can convert one equation into another one (3x-3y=-18---> x-y=-6, ---->y=x+6)
second one is one solution, because
y=-4x+11 and y=11+6x,--->-4x+11=11+6x, -4x-6x=0, x=0
third one
y =-2x+5 and y=-7-2x ,-2x+5=-7-2x, --->5=-7 false , no solutions

X*2 +5 =41
Subtract 5 from both sides
X*2=36
Square root of 36 is 6
X=6
Solve
6*2+5 =41
This’s correct!
