Solve -6.63*10^-34*3*10^9/434=2.18*10^-18x

$$- 6.63 \times 10 ^ { - 34 } \times \frac { 3 \times 10 ^ { 9 } } { 434 } = 2.18 \times 10 ^ { - 18 } x$$

Solve for x

$$x=-\frac{1989}{946120000000}\approx -2.102270325 \cdot 10^{-9}$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 434.

$$-6.63\times 10^{-34}\times 3\times 10^{9}=946.12\times 10^{-18}x$$

Calculate 10 to the power of -34 and get \frac{1}{10000000000000000000000000000000000}.

$$-6.63\times \frac{1}{10000000000000000000000000000000000}\times 3\times 10^{9}=946.12\times 10^{-18}x$$

Multiply -6.63 and \frac{1}{10000000000000000000000000000000000} to get -\frac{663}{1000000000000000000000000000000000000}.

$$-\frac{663}{1000000000000000000000000000000000000}\times 3\times 10^{9}=946.12\times 10^{-18}x$$

Multiply -\frac{663}{1000000000000000000000000000000000000} and 3 to get -\frac{1989}{1000000000000000000000000000000000000}.

$$-\frac{1989}{1000000000000000000000000000000000000}\times 10^{9}=946.12\times 10^{-18}x$$

Calculate 10 to the power of 9 and get 1000000000.

$$-\frac{1989}{1000000000000000000000000000000000000}\times 1000000000=946.12\times 10^{-18}x$$

Multiply -\frac{1989}{1000000000000000000000000000000000000} and 1000000000 to get -\frac{1989}{1000000000000000000000000000}.

$$-\frac{1989}{1000000000000000000000000000}=946.12\times 10^{-18}x$$

Calculate 10 to the power of -18 and get \frac{1}{1000000000000000000}.

$$-\frac{1989}{1000000000000000000000000000}=946.12\times \frac{1}{1000000000000000000}x$$

Multiply 946.12 and \frac{1}{1000000000000000000} to get \frac{23653}{25000000000000000000}.

$$-\frac{1989}{1000000000000000000000000000}=\frac{23653}{25000000000000000000}x$$

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

$$\frac{23653}{25000000000000000000}x=-\frac{1989}{1000000000000000000000000000}$$

Multiply both sides by \frac{25000000000000000000}{23653}, the reciprocal of \frac{23653}{25000000000000000000}.

$$x=-\frac{1989}{1000000000000000000000000000}\times \frac{25000000000000000000}{23653}$$

Multiply -\frac{1989}{1000000000000000000000000000} and \frac{25000000000000000000}{23653} to get -\frac{1989}{946120000000}.

$$x=-\frac{1989}{946120000000}$$
