Solve a=5-(7-[1-6-9)]:25=

$$a = 5 - ( 7 - [ 1 - 6 - 9 ) ] : 25 =$$

Solve for a

$$a = \frac{104}{25} = 4\frac{4}{25} = 4.16$$

Steps for Solving Linear Equation

Subtract 6 from 1 to get -5.

$$a=5-\frac{7-\left(-5-9\right)}{25}$$

Subtract 9 from -5 to get -14.

$$a=5-\frac{7-\left(-14\right)}{25}$$

The opposite of -14 is 14.

$$a=5-\frac{7+14}{25}$$

Add 7 and 14 to get 21.

$$a=5-\frac{21}{25}$$

Convert 5 to fraction \frac{125}{25}.

$$a=\frac{125}{25}-\frac{21}{25}$$

Since \frac{125}{25} and \frac{21}{25} have the same denominator, subtract them by subtracting their numerators.

$$a=\frac{125-21}{25}$$

Subtract 21 from 125 to get 104.

$$a=\frac{104}{25}$$

Assign a

$$a≔\frac{104}{25}$$
