To solve the equation (-3a = 24), you need to isolate (a). Start by dividing both sides of the equation by (-3): [ a = \frac{24}{-3} ] This simplifies to (a = -8). Thus, the solution is (a = -8).
a-16 = a/4+2 Multiply all terms by 4: 4a-64 = a+8 4a-a = 8+64 3a = 72 a = 24
It is an equation because: a = 6
3a + 11 = 7a - 13 subtract 3a from each side 3a - 3a + 11 = 7a - 3a - 13 11 = 4a - 13 add 13 to each side 11 + 13 = 4a - 13 + 13 24 = 4a divide each sides integer by 4 24/4 = (4/4)a 6 = a -------------check in original equation 3(6) + 11 = 7(6) - 13 18 + 11 = 42 - 13 29 = 29 ----------------checks out
-21 = 9a - 15 - 3a -6 = 6a -1 = a

3a x 2a =24
An equation.

Divide both sides of the equation by 3, resulting in a on the left side and 1022/3 on the right. (Simplify as you wish.)

36 -20 = 16
yes, one in which a = 6
In the equation ( 81 = 3a - 8a - 4a ), the variable ( a ) represents an unknown quantity that we need to solve for. To simplify the right side, we combine the terms: ( 3a - 8a - 4a = -9a ). This gives us the equation ( 81 = -9a ). Solving for ( a ) involves dividing both sides by -9, resulting in ( a = -9 ).
It is, in fact, an identity - which is an equation which is true for all values of the variable.
