Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 300}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{110 + 0.70x = 50 + 0.90x}[/tex]
Move 0.90x to left hand side and change it's sign
⇒[tex] \sf{0.70x - 0.90x + 110 = 50}[/tex]
Move 110 to right hand side and change it's sign
⇒[tex] \sf{0.70x - 0.90x = 50 - 110}[/tex]
Collect like terms
⇒[tex] \sf{ - 0.2x = 50 - 110}[/tex]
Calculate
⇒[tex] \sf{ - 0.2x = - 60}[/tex]
Divide both sides of the equation by -0.2
⇒[tex] \sf{ \frac{ - 0.2x}{ - 0.2} = \frac{ - 60}{ - 0.2} }[/tex]
Calculate
⇒[tex] \sf{x = 300}[/tex]
Hope I helped!
Best regards!!
