Answer:
6x - 9y = -12
Step-by-step explanation:
2x - 3y = -4 multiply both sides by 3 by adding paranthesis to represent this
3( 2x - 3y ) = 3 (-4) Then use distributive property for the left side equation
6x - 9y = -12 Finally just multiply -4 by 3 and you get this equation

Step-by-step explanation:
Given:
Tina cut 3 wood boards each into 4 equal pieces.
She used 3 of the pieces for a craft.
Question asked:
What fraction of the boards does she have left ?
Write this fraction as a mixed number.
Solution:
<em><u>As she cuts 3 wood board each into 4 equal pieces :-</u></em>
Total number of equal pieces = 
Pieces of wood used = 3
Remaining pieces = 12 - 3 = 9
<h3>
<u><em>Now, we will write these 9 pieces in terms of number of wood boards</em></u>.</h3>
<u>By unitary method:</u>
4 pieces constitute = 1 wood board
1 piece constitute = 
9 pieces constitute = 
<em>Now, convert it into mixed fraction:</em>

Therefore, fraction of the boards she have left is
