Question

Tom is given the equation 10x+15=20 to solve. He says the solution is 1/2 . Which reason justifies his solution?(1 point) Responses Tom says that to solve the equation you first divide by 10 and then subtract 15. Tom says that to solve the equation you first divide by 10 and then subtract 15. Tom says that to solve the equation you first subtract 15 and then multiply by 10. Tom says that to solve the equation you first subtract 15 and then multiply by 10. Tom says that to solve the equation you first add 15 and then divide by 10. Tom says that to solve the equation you first add 15 and then divide by 10. Tom says that to solve the equation you first subtract 15 and then divide by 10.

Answer 1

Tom's solution is not correct. The equation 10x + 15 = 20 can be solved by first subtracting 15 from both sides and then dividing by 10. Therefore, the correct reasoning would be "Tom says that to solve the equation you first subtract 15 and then divide by 10."
