Which of the following equations have infinitely many solutions? i. 6(2 x + 4) = 3(4 x + 8) ii. 0.5 (8 x + 4) = 4 x + 2 iii. 7 x + 8 = 7( x + 8) iv. 3 x + 4 = 7 x - 2 v. 2(6 x + 4) = 4(3 x + 2)

For us to have infinitely many solutions, we need to have one of two situations happening, when we solve for x we get 0=0... this is because both of our sides need to be the same, then it doesnt matter what x equals, so it can be anything!

solve each equation and see if everything ends up canceling out!

The answer is b: step 2.
