Question

To use the elimination method, you can subtract the two equations in a system of equations to eliminate one of the variables.

Subtract the two equations,
x+ y = 7
2 - 3y = 5
What is the resulting equation?

Answer 1

• The resulting equation is '4y = 2'.

Explanation:

Hi there... I understood your "2" as a typo and considering it as x.

• x + y = 7

-(x - 3y = 5)

• x + y = 7

-x + 3y = -5

• => 4y = 2

Hence, the resulting equation is '4y = 2'

Hoped this helped.

Answer 2

• (6.5, 0.5)

Explanation:

It seems a typo:

• x + y = 7
• x - 3y = 5

Subtract to eliminate x and solve for y:

• x + y - x + 3y = 7 - 5
• 4y = 2
• y = 0.5

Now you can find the value of x:

• x + 0.5 = 7
• x = 6.5
