First youre going to want to distribute that 2 into the 5x + 1. So that makes the equation 3x + 7x + 1 = 10x + 2 + 2
Next combine the like terms on each side (like combining the 3x and 7x to make 10x). This makes the equation 10x + 1 = 10x + 4
Then we com into a problem when we isolate the variable. This is because we subtract 1 on both side to make it 10x = 10x + 3. We would then subtract 10x from both sides. This however makes that 0 = 3. Knowing this not to be true, the answer is no solution.
