Find the solution set of 42x - 3plus 7 equals 8x plus 5?

Answer 1

You said that 42x - 3 + 7 = 8x + 5 .

Combine the like terms on the left side (the -3 and the +7):

42x + 4 = 8x + 5

Subtract 4 from each side:

42x = 8x + 1

Subtract 8x from each side:

34x = 1

Divide each side by 34:

x = 1/34

The solution set is: {34}
