Question

solve this equation algebraic graphically X + 4 Y equals to9. 12x minus 3 y equals to 6 ​

Answer 1

Answer:

x = 1 , y = 2

Step-by-step explanation:

Answer 2

Given equations:

• x + 4y = 9
• 12x - 3y = 6

Let the equation be as

• x + 4y = 9...Equation 1
• 12x - 3y = 6...Equation 2

~ Firstly let us put x as 0 in equation 1.

→ x + 4y = 9

→ 0 + 4y = 9

→ 4y = 9

→ y = 9/4

→ y = 2.3

• Therefore, coordinates (0,2.3)

~ Now let's put y as 0 in equation 1.

→ x + 4y = 9

→ x + 4(0) = 9

→ x + 0 = 9

→ x = 9

• Therefore, coordinates (9,0)

~ Now let's put x as 0 in equation 2.

→ 12x - 3y = 6

→ 12(0) - 3y = 6

→ 0 - 3y = 6

→ -3y = 6

→ y = 6/-3

→ y = -2

• Therefore, coordinates (0,-2)

~ Now let's put y as 0 in equation 2.

→ 12x - 3y = 6

→ 12x - 3(0) = 6

→ 12x - 0 = 6

→ 12x = 6

→ x = 6/12

→ x = 1/2

→ x = 0.5

• Therefore, coordinates (0.5,0)

They intersect at (1,2) $\:$
