Solve 40/100+40=0.69x/100

$$\frac { 40 } { 100 + 40 } = \frac { 0.69 x } { 100 }$$

Solve for x

$$x = \frac{20000}{483} = 41\frac{197}{483} \approx 41.407867495$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 100.

$$\frac{5}{7}\times 40=0.69x$$

Express \frac{5}{7}\times 40 as a single fraction.

$$\frac{5\times 40}{7}=0.69x$$

Multiply 5 and 40 to get 200.

$$\frac{200}{7}=0.69x$$

Swap sides so that all variable terms are on the left hand side.

$$0.69x=\frac{200}{7}$$

Divide both sides by 0.69.

$$x=\frac{\frac{200}{7}}{0.69}$$

Express \frac{\frac{200}{7}}{0.69} as a single fraction.

$$x=\frac{200}{7\times 0.69}$$

Multiply 7 and 0.69 to get 4.83.

$$x=\frac{200}{4.83}$$

Expand \frac{200}{4.83} by multiplying both numerator and the denominator by 100.

$$x=\frac{20000}{483}$$
