Question

Solve by any method -7x-4y=-4. 14x+10y=24

Answer 1

Answer: x=−4.895105y

Explanation:

−7x−4y=−4.14x+10y

Step 1: Add 4.14x to both sides.

−7x−4y+4.14x=−4.14x+10y+4.14x

−2.86x−4y=10y

Step 2: Add 4y to both sides.

−2.86x−4y+4y=10y+4y

−2.86x=14y

Step 3: Divide both sides by -2.86.

−2.86x

−2.86

=

14y

−2.86

x=−4.895105y
