Solve 0.7=5*x/220+x

$$0.7= \frac{ 5 \times x }{ 220+x }$$

Solve for x

$$x = \frac{1540}{43} = 35\frac{35}{43} \approx 35.813953488$$

Steps for Solving Linear Equation

Variable x cannot be equal to -220 since division by zero is not defined. Multiply both sides of the equation by x+220.

$$0.7\left(x+220\right)=5x$$

Use the distributive property to multiply 0.7 by x+220.

$$0.7x+154=5x$$

Subtract 5x from both sides.

$$0.7x+154-5x=0$$

Combine 0.7x and -5x to get -4.3x.

$$-4.3x+154=0$$

Subtract 154 from both sides. Anything subtracted from zero gives its negation.

$$-4.3x=-154$$

Divide both sides by -4.3.

$$x=\frac{-154}{-4.3}$$

Expand \frac{-154}{-4.3} by multiplying both numerator and the denominator by 10.

$$x=\frac{-1540}{-43}$$

Fraction \frac{-1540}{-43} can be simplified to \frac{1540}{43} by removing the negative sign from both the numerator and the denominator.

$$x=\frac{1540}{43}$$
