4.9:7=0.7

Answer 3

To solve the equation 19x - 12x = 4.9, you need to combine the like terms on the left side of the equation and isolate the variable x.

Step 1: Combine like terms 19x - 12x is equal to 7x. So, the equation becomes: 7x = 4.9

Step 2: Isolate the variable x To isolate x, you need to get rid of the coefficient 7 attached to it. Since 7 is multiplied by x, you can undo this operation by dividing both sides of the equation by 7:

7x / 7 = 4.9 / 7

Simplifying:

x = 0.7

So, the solution to the equation is x = 0.7.
