How do you solve $7 a - 17 = 4 a + 1$ $7a-17=4a+1$ ?

1 Answer

Oct 26, 2016

$a = 6$ $a = 6$

Explanation:

You solve for $a$ $a$ as follows keeping the equation balanced:

$7 a - 17 = 4 a + 1$ $7a - 17 = 4a + 1$

$7 a - 4 a - 17 + 17 = 4 a - 4 a + 1 + 17$ $7a - 4a -17 + 17 = 4a - 4a + 1 + 17$

$3 a = 18$ $3a = 18$

$\frac{3 a}{3} = \frac{18}{3}$ $(3a)/3 = 18/3$

$a = 6$ $a = 6$
