fill in the blanks to make the equation get an 1.infinite solution,and 2.no solution: 7x+3x+10=-2(_x+_)

Answer 1

-2(-5x+ -5) for infinite solutions

-2(-5x+ -4) for no solution

7x + 3x + 10

=10x + 10 = -2(-5x-5). Graphically, they're the same line, so infinite "intersections"/solutions

-2(-5x+b) is parallel to 10x+10 for any b not =-5. parallel lines never intersect, so no solution
