Answer:

4x - 3y + 6z.

Step-by-step explanation:

He wrote 62 instead of 6z on the first line.

He made 2 mistakes on the last line:

He didn't subtract the x terms, there was no term = 5.

The -3y + 6z does not simplify to 3yz, the terms have an add process not a multiply.

The correct solution is

5x - x - 3y + 6z

= 4x - 3y + 6z.

Length and width of 1 rectangle = 6 : 8

Dimensions of the other rectangle = ?

Let length and width of the other rectangle be x : y

According to the question:

Help me on the first question pls

Margaret [11]

To do the first question, simplify the equation, putting like terms together, by adding and subtracting to do this.

Then looking at the equation that you solved for, look and see if there are any other equations that are related in some way to the original solved equation.

Pay close attention to the positive and negative signs.
