Rewrite each expression by combining like terms.
Evgesh-ka [11]

Answer:

5y-2xy

Step-by-step explanation:

For the first expression, we can multiply 5 by y to get 5y. Thats all we can simplify it though, because xy is not equal to x or y.

For the second equation, we can easily add the variables to simplify. 6q-6

The graph below shows a system of equations: Draw a line labeled y equals minus x plus 5 by joining the ordered pairs 0, 5 and 5
Montano1993 [528]

Answer:

The x-coordinate of the solution is x=3

Step-by-step explanation:

we have

y=-x+5 ------> equation A

y=x-1 ------> equation B

Solve the system of equations by substitution

Substitute equation B in equation A and solve for x

x-1=-x+5

x+x=5+1

2x=6

x=3

Find the value of y

y=x-1  ------> y=3-1=2

The solution of the system of equations is the point (3,2)

therefore

The x-coordinate of the solution is x=3
