Question

Solve it in algebraically
y= 4x – 11
y=-8x + 13

Answer 1

y=4x−11

Step 1: Flip the equation.

4x−11=y

Step 2: Add 11 to both sides.

4x−11+11=y+11

4x=y+11

Step 3: Divide both sides by 4.

`(4x)/(4)` =
`(y+11)/(4)`

x=
`(1)/(4) y` +
`(11)/(4)`

y=-8x + 13

Step 1: Flip the equation.

−8x+13=y

Step 2: Add -13 to both sides.

−8x+13+−13=y+−13

−8x=y−13

Step 3: Divide both sides by -8.

`(-8x)/(8)` =
`(y- 13)/(-8)`

x=
`(-1)/(8)y` +
`(13)/(8)`
