4.5 = 2a
Solving
4.5 = 2a
Solving for variable 'a'.
</span>
<span>Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation.
4.5 + -2a = 2a + -2a
</span>
<span>Combine like terms: 2a + -2a = 0
4.5 + -2a = 0
</span>
<span>Add '-4.5' to each side of the equation.
4.5 + -4.5 + -2a = 0 + -4.5
</span>
<span>Combine like terms: 4.5 + -4.5 = 0.0
0.0 + -2a = 0 + -4.5
-2a = 0 + -4.5
</span>
<span>Combine like terms: 0 + -4.5 = -4.5
-2a = -4.5
Divide each side by '-2'.
a = 2.25
Simplifying
a = 2.25
Let's check: 2 x 2.25 = 4.5
Next time, follow these steps and you will pass
