Solve -6 r/4 = 7 - ScanMath

Evaluate

- (6 \times \frac{r}{4}) = 7

Evaluate

More Steps

- \frac{3 r}{2} = 7

Simplify the expression

- \frac{3}{2} r = 7

Multiply both sides of the equation by LCD

- \frac{3}{2} r \times 2 = 7 \times 2

Simplify the equation

- 3 r = 7 \times 2

Simplify the equation

- 3 r = 14

Square both sides of the equation

(- 3 r)^{2} = 1 4^{2}

Evaluate

9 r^{2} = 1 4^{2}

To covert the equation to rectangular coordinates using conversion formulas,substitute x^{2} + y^{2} for r^{2}

9 (x^{2} + y^{2}) = 1 4^{2}

Evaluate the power

9 (x^{2} + y^{2}) = 196

Solution

9 x^{2} + 9 y^{2} = 196
