How do you solve a system of equations approximately using graphs and tables

Solve for y and x of the given equations and draw graph  for each equation , then find their intersect points of the given equations .

Step-by-step explanation:

suppose, we take system of equations

x+y=5(I equation)

x-y=5(II equation)

Now , we take I equation x+y=5

Draw a table for this equation By following steps

Put x=0 in I equation then we get value of y =5 from I equation

Now , put y=0 in the I equation we get value of x=5 from I equation.

Now , we get two points (0,5) and (5,0) and plot the graph for I equation.

I  equation x+y=5 interscet x -axis at x=5 and y- axis at y=5 .

Now, w etake II equation x-y=5  

Now , put x=0 in the II equation then  we get  value of y =-5

Again, put y=0 in the II equation x-y=5 then we get value of x =5.

We get  two points (0,-5) and (5,0) for II equation and plot graph .

the common point is (5,0) of two equations.Hence , the solution of two equation is (5,0).

Therefore, we can solve system of equations in this way.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
