Question

how to solve
0.2a=46-0.03a

Answer 1

0.2a=46-0.03a

0.2a+0.03a=46=0.23a=46

a=46/0.23

or a=46×10/23

or a=2×10=20

a=20

Answer 2

Answer:

$0.2a = 46 - 0.03a \\ 0.2a + 0.03a = 46 \\ 0.23a = 46 \\ or \\ \frac{23}{100} a = 46 \\ \frac{23a}{100} = 46 \\ 23a = 46 \times 100 \\ a = \frac{_{2 \: \: } \cancel{ 46 }\times 100}{ \cancel{ 23}_{ \: \: 1} } \\ a = \underline{ \underline{ 200}}$
