The answer to this question is X= -8
First do the distributive property and you get : -70 + 21x= -238
Then you add 70 to both sides : 21x= -168
Then you divide -168 with 21 and get the answer of -8
To solve the above equation, first step is to use the distribution property. So,
7(-10+3x)=-238
-70 + 21x = -238
-70 + 21x + 70 = -238 + 70 Add 70 to each sides of the equation.
21x = -168
[tex] \frac{21x}{21} =-\frac{168}{21} [/tex]
So, x = -8
