Pick two that have infinite solutions and two that have one solution and two that have no solutions

Question

2x+3=2×+7
5x+5=5×+4
7x+3=7×+3
3x+18=5x+8
4×+22=8×+10
3(4x+8)=4(3x+6)

Answer 1

Two equations that have infinite solutions are:
1) 7x+3=7×+3 (since both sides of the equation are equal, no matter the value of x)
2) 3(4x+8)=4(3x+6) (if we simplify both sides of the equation, we get 12x+24=12x+24, which is always true)

Two equations that have one solution are:
1) 2x+3=2×+7 (if we solve this equation, we get x=-2)
2) 5x+5=5×+4 (if we solve this equation, we get x=1)

Two equations that have no solutions are:
1) 3x+18=5x+8 (if we solve this equation, we get x=not possible)
2) 4×+22=8×+10 (if we solve this equation, we get x=not possible)
