Question

Using complete sentences, explain what might happen if the order of operations was used to solve a literal equation.

Answer 1

\[\frac{ S }{ 4 }=\frac{ 4V^{2} }{ 4? }\]

Answer 2

you should not use order of operating when solving a literal equation. it complicates the isolation process

Answer 3

for example, take below equation and try to solve using 'order of operations' :-

Solve the literal equation : 2x-3 = 7

Answer 4

PEMDAS

first comes Multiplication, since 2 is attached to x, to isolate x, we divide the whole equation with 2 :

2x-3 = 7
/2 /2

x - 3/2 = 7/2

Answer 5

Next, add 3/2 both sides

x - 3/2 = 7/2
+ 3/2 +3/2

Answer 6

x = 7/2 + 3/3

x = 10/2

x = 5

Answer 7

Obviously this is a bit complicated. You sure know the the other easy way to solve this... dont you ?
