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]
