How do you solve this linear equation 4x-7y equals -4 x plus y equals 0?

Answer 1

4x-7y = -4

4(x+y = 0)

Mutiply all terms in the bottom equation by 4:

4x-7y = -4

4x+4y = 0

Subtract the bottom equation from the top equation:

-11y = -4

Divide both sides by -11 remembering that a minus divided into a minus becomes a plus:

y = 4/11

Substitute the value of y into the original equations to find the value of x:

Therefore: x = -4/11 and y = 4/11
