Answer: x= -117
Step-by-step explanation:
28*9 = 18 + (-2x)
252 = 18 + (-2x)
252 - 18 = 18 - 18 + (-2x)
234 = -2x
234/-2 = -2x/-2
x = -117
Hello!
The answer to your problem is [tex]x=-117[/tex]
Simplify both sides of the equation
[tex](28)(9)=18-2x\\252=18+-2x\\252=-2x+18[/tex]
Flip the equation
[tex]-2x+18=252[/tex]
Subtract 18 from both sides
[tex]-2x+18-18=252-18\\-2x=234[/tex]
Divide both sides by -2 (Final Step)
[tex]-2x/-2=-234/-2[/tex]
Get your answer
[tex]x=-117[/tex]
