The equation 1.6x – 2.2 = 1.4x can be transformed to form which of the following expressions?

3.0x = 2.2
0.2x = –2.2
3.0x = –2.2
0.2x = 2.2

Question

The equation 1.6x – 2.2 = 1.4x can be transformed to form which of the following expressions? 

 	
	3.0x = 2.2
	0.2x = –2.2
	3.0x = –2.2
	0.2x = 2.2

anonymous · Answer

An easy way to solve this is to isolate x by itself. You always want to get the variable by itself to solve!

Combine like terms first, so subtract 1.4x from both sides. 

1.6x -2.2 -1.4x = 1.4x - 1.4x

Can you solve this so far and I'll help you with the next step once you finish?
