Solve 78=1/2x(64+13)

$$78= \frac{ 1 }{ 2 } x(64+13)$$

Solve for x

$$x = \frac{156}{77} = 2\frac{2}{77} \approx 2.025974026$$

Steps for Solving Linear Equation

Add 64 and 13 to get 77.

$$78=\frac{1}{2}x\times 77$$

Multiply \frac{1}{2} and 77 to get \frac{77}{2}.

$$78=\frac{77}{2}x$$

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

$$\frac{77}{2}x=78$$

Multiply both sides by \frac{2}{77}, the reciprocal of \frac{77}{2}.

$$x=78\times \frac{2}{77}$$

Express 78\times \frac{2}{77} as a single fraction.

$$x=\frac{78\times 2}{77}$$

Multiply 78 and 2 to get 156.

$$x=\frac{156}{77}$$
