Solve x: 5x + 3y = 15

Evaluate

x \div 5 x + 3 y = 15

Find the domain

More Steps

x \div 5 x + 3 y = 15, x \neq = 0

Divide the terms

More Steps

\frac{1}{5} + 3 y = 15

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

3 y = 15 - \frac{1}{5}

Subtract the numbers

More Steps

3 y = \frac{74}{5}

Multiply by the reciprocal

3 y \times \frac{1}{3} = \frac{74}{5} \times \frac{1}{3}

Multiply

y = \frac{74}{5} \times \frac{1}{3}

Multiply

More Steps

y = \frac{74}{15}

Check if the solution is in the defined range

y = \frac{74}{15}, x \neq = 0

Solution

{x \neq = 0 y = \frac{74}{15}

Alternative Form

{x \neq = 0 y = 4.9 \dot{3}
