Question

Sasha solved an equation. Her work is shown below. Explain Sasha's error. Then, show the correct way to solve.

h divided by seven equals six. Add seven to both sides: h divided by seven plus seven equals six plus seven, so h equals thirteen.

Answer 1

\[h/7 = 6\]

adding 7 to both sides will give h/7 + 7 = 13

that does not equal 6 + 7.....you need to multiply both sides by 7

h/7 times 7 gives h and 6 times 7 is 42 so h is 42

Answer 2

thx

Answer 3

\[\frac{ h }{ 7 } = 6\]
\[\frac{ h }{ 7 } + 7 = 6 + 7\]
\[\frac{ h+49 }{ 7 } = 13\]
\[h = 13*7 - 49\] = 42
