Subtract the 1a from the 7a. 
1a + 18 = 7a
-1a          -1a

you're then left with 18=6a. divide the 6 with the 18 to cancel out.
18=6a
/6a /6a

18 divided by 6 is 3. So your answer is a=3

SIMPLIFY 7/10+1/4-1/5=
Strike441 [17]

Answer:

3/4

Step-by-step explanation:

Q = \frac{7}{10} +\frac{1}{4} -\frac{1}{5}      

{the smallest common multiple of 10, 4 and 5 is 5×2×2 = 20 (denominator)}

Q =\frac{7×2}{10×2} +\frac{1×5}{4×5} -\frac{1×4}{5×4}

=\frac{14}{20} +\frac{5}{20} -\frac{4}{20}

=\frac{14+5-4}{20}

=\frac{15}{20}

=\frac{3×5}{4×5}

=\frac{3}{4}
