Answer explanation

Sorry that one was so long, but it is great practice! Make sure to solve difficult math equations to exercise your brain!

9.2r+5.514= 158.234

• v= 14.8591

• v= -15.88968

• v= 15.88968

• v=17.592

-5.4-7.8x= -78.408

• k= 0.4264

• k= -2.471

• k= -0.4264

• k= 1.325

• x= 6.1837

• x= 4.9782

• x= -4.9782

• x= 5.5979

• n= -11.807

• n= 10.6003

• n= 11.807

• n= -13.425
