Hello.
For the first one its
x = -0.2 + -0.4y
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation
. 5x + 2y + -2y = -1 + -2y Combine like terms: 2y + -2y = 0 5x + 0 = -1 + -2y 5x = -1 + -2y
Divide each side by '5'. x = -0.2 + -0.4y
For the second its
x=−y+2
Step 1: Flip the equation.−x+2=y
Step 2: Add -2 to both sides.−x+2+−2=y+−2−x=y−2
Step 3: Divide both sides by -1.−x−1=y−2−1x=−y+2
Have a nice day
