Solve 4y-16x=20 - ScanMath

Câu hỏi

Function

Find the x -intercept/zero

Find the y-intercept

Find the slope

x = - \frac{5}{4}

Evaluate

4 y - 16 x = 20

To find the x -intercept,set y =0

4 \times 0 - 16 x = 20

Any expression multiplied by 0 equals 0

0 - 16 x = 20

Removing 0 doesn't change the value,so remove it from the expression

- 16 x = 20

Change the signs on both sides of the equation

16 x = - 20

Divide both sides

\frac{16 x}{16} = \frac{- 20}{16}

Divide the numbers

x = \frac{- 20}{16}

Giải pháp

Solve the equation

Solve for x

Solve for y

x = \frac{- 5 + y}{4}

Evaluate

4 y - 16 x = 20

Move the expression to the right-hand side and change its sign

- 16 x = 20 - 4 y

Change the signs on both sides of the equation

16 x = - 20 + 4 y

Divide both sides

\frac{16 x}{16} = \frac{- 20 + 4 y}{16}

Divide the numbers

x = \frac{- 20 + 4 y}{16}
