Solve 2x+2y-5=0 - ScanMath

Question

Function

Find the x -intercept/zero

Find the y-intercept

Find the slope

x = \frac{5}{2}

Evaluate

2 x + 2 y - 5 = 0

To find the x -intercept,set y =0

2 x + 2 \times 0 - 5 = 0

Any expression multiplied by 0 equals 0

2 x + 0 - 5 = 0

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

2 x - 5 = 0

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

2 x = 0 + 5

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

2 x = 5

Divide both sides

\frac{2 x}{2} = \frac{5}{2}

Solution

x = \frac{5}{2}

Solve the equation

Solve for x

Solve for y

x = \frac{- 2 y + 5}{2}

Evaluate

2 x + 2 y - 5 = 0

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

Subtract the terms

More Steps

Evaluate

0 - (2 y - 5)

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

0 - 2 y + 5

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

- 2 y + 5

2 x = - 2 y + 5

Divide both sides

\frac{2 x}{2} = \frac{- 2 y + 5}{2}

Solution

x = \frac{- 2 y + 5}{2}

r = \frac{5}{2 cos ( θ ) + 2 sin ( θ )}

Evaluate

2 x + 2 y - 5 = 0

To convert the equation to polar coordinates,substitute x for r cos (θ) and y for r sin (θ)
