Algebra math pls help find like terms

-2x and 4x

8yz and -21yz

-25 and 17

and 12

-3xy and -5xy

5y and 3y

Step-by-step explanation:

Like terms are terms with the same variables and powers.

Which basically means...

Terms with x in them can only match with other terms with only x in them, such as -2x and 4x, but they can't match with other terms with other variables that are not x such as -2x can't match with 3y, because there's nothing common (alike) between them.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

yess

idk whyy this is happening, i cant even read my notification bc i keep getting errors
