The solution is (5,2)
Step-by-step explanation:
From the third column the equation for sum of equivalent system is given as;
8x = 40
divide both sides by 8 to get value of x
8x/8 = 40/8
x=5
Using the value of x in the fifth column's first equation will be;
4x +4y =28
4(5) + 4y =28
20 +4y =28
4y= 28-20
4y=8
divide both sides by 4 to get y
4y/4 =8/4
y=2
The solution is x=5 and y=2 written as (5,2)

Step-by-step explanation:
option C is the correct answer of this question
Answer:

Step-by-step explanation:
The y-intercept is where x is 0 (0,y)
The x-intercept is where y is 0 (x,0)
Insert 0 as the value for x to find the corresponding y value:

Simplify multiplication:

Isolate the variable. Divide both sides by 4:

Make the variable positive. Multiply both sides by -1:

The y-intercept is at
.
Insert 0 as the value for y to determine the value of x:

Simplify multiplication:

Isolate x. Divide both sides by 5:

Multiply both sides by -1:

The x-intercept is at
