Question

5(2x+7) - 3x = 7(x + 5) how many solutions does it have??

Answer 1

Infinite real solutions

Explanation:

5(2x+7) - 3x = 7(x+5)

lets expand

10x+35 - 3x = 7x + 35

combine like terms

7x = 7x -- i subtracted 35 on each side and combined 10x - 3x

we see that

7x = 7x

Therefore, there is infinite real solutions.
