Hey there!!
We have:
... f(x) = -12x + 7
... g(x) = 4x - 9
<em>Now, we will have to find f(x) = g(x)</em>
... f(x) = g(x)
<em>... </em>-12x + 7 = 4x - 9
<em>... </em>9 + 7 = 4x + 12x
<em>... </em>16 = 16x
<em>... </em>x = 16/16
<em>... x = 1 </em>
<em>Hence, the value of 'x' is 1. </em>
<em>Hope this helps! </em>
<em>Happy Thanksgiving! :) </em>
Answer: 7
Step-by-step explanation:
First set up your equation 40+21x=187
