Solve the following System of Equations by Elimination. Place your answer in coordinate form. 4x−2y=4
2x+6y=16

Step-by-step explanation:

we multiply one of the equations (left and right) by a factor, so that either the x term or the y term are equal to the other equation.

and then we subtract one equation from the other.

4x - 2y = 4

2x + 6y = 16

for me the x terms immediately catch my eye.

so, I multiply the second equation by 2.

4x + 12y = 32

now for the subtraction :

4x - 2y = 4

- 4x + 6y = 16

0 - 8y = -12

8y = 12

y = 12/8 = 3/2

=> in the first equation

4x + 2× 3/2 = 4

4x + 3 = 4

4x = 1

x = 1/4

so, the solution is (1/4, 3/2)

5x+2x=49

7x=49

x=7. 35 apples
