You can
put this solution on YOUR website! 4(3q + 2) = 2(6q + 4)
Use the distributive principle to multiply the outer
multiplier by each inner term inside the parentheses:
4·3q + 4·2 = 2·6q + 2·4
12q + 8 = 12q + 8
Subtract 8 from both sides
12q = 12q
Subtract 12q from both sides,
writing the left side as 0q
0q = 0
Any number when substituted for
q will give a true equation. That's
because 0 times any number will
always equal to 0. So this kind
of an equation is called
an "identity". Every number is a
solution to it.
