Multiply the answer by 100.
Answer:
a = 3/28
Step-by-step explanation:
<em>To start solving for a variable, you need to isolate it.</em>
-4/3b = 4a
<em>-4/3 divided by 4 equals -4/12 or </em><em>-1/3</em>
a = -1/3b
<em>To completely solve for </em><em>a</em><em> we need to plug it back in and solve for </em><em>b</em><em>.</em>
b = (4(-1/3b)) - 3/4
b = -4/3b - 3/4
7/3b = -3/4
b = -9/28
<em>Finally, we can plug </em><em>b</em><em> back in to the previous equation we got for </em><em>a</em><em> to solve for </em><em>a</em><em>.</em>
a = -1/3(-9/28)
a = 3/28
<em>Furthermore, we can check if this is correct by plugging in </em><em>3/28</em><em> for </em><em>a</em><em> into the original problem and see if we get what we got for </em><em>b</em><em> (</em><em>-9/28</em><em>)</em>
