Answer:
infinite solutions
Explanation:
6x + 30 + 4x = 10(x + 3)
distribute the 10:
6x + 30 + 4x = 10x + 30
combine like terms:
10x + 30 = 10x + 30
subtract 10x from both sides:
30 = 30
Because the variable cancels out and leaves a true statement, there are infinite solutions. It will be true no matter what value you plug in for x.
