Answer:
2x - 106 (or x - 53) i hope this helps! :)
Step-by-step explanation:
-7(x + 10) + 9(x - 4)
you need to distribute the -7 with the x and the 10
-7x - 70 + 9(x - 4)
distribute the 9 with the x and -4
-7x - 70 + 9x - 36
combine like terms first the x values
2x - 70 - 36
combine like terms
2x - 106
i dont remember if you divide both by two or not
x - 53 if so x - 53 is the answer
