Question

Solve each system of equations algebraically
1. y=x+5 y=6 2. y=x+12 y= -18 3. y=x-10 y= -12

Answer 1

Explanation:

ky=x+5y 62y=x

Step: Solvey=x+5yfor x:

y=x+5y

y+−x=x+5y+−x(Add -x to both sides)

−x+y=5y

−x+y+−y=5y+−y(Add -y to both sides)

−x=4y et's solve for x.

y=x+12y

Step 1: Flip the equation.

x+12y=y

Step 2: Add -12y to both sides.

x+12y+−12y=y+−12y

x=−11y

Answer:

x=−11y
