Question

Which equation is equivalent to the given equation?7m + 11 = -4(2m + 3)A.—m1-15m= –23C.15m-23-m = -1

Answer 1

We have the following equation given:

$7m+11\text{ = }-4(2m+3)$

We can distribute the terms in the right part of the equation and we got

$7m+11=-8m-12\text{ }$

Now we can add 8m in both sides of the equation and we got:

$7m+8m+11=\text{ }-8m+8m\text{ }-12$$15m\text{ +11 = }-12$

And now we can add 12 in both sides of the equation and we got:

$15m+11+12=-12+12=0\text{ }$$15m\text{ +23 =0}$

And finally we can subtract 23 from both sides of the equation and we got:

$15\text{ m = }-23$

And the best option would be C
