Svana wants to solve the equation 12x – 1.0675 = 3x – 4.145. She uses a graphing program to graph the equations y = 12x – 1.0675 and y = 3x – 4.145. Use the graph to find the solution of 12x – 1.0675 = 3x – 4.145.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
