110 +0.70x = 50+ 0.90x​
timurjin [86]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x = 300}}}}}

Step-by-step explanation:

\sf{110 + 0.70x = 50 + 0.90x}

Move 0.90x to left hand side and change it's sign

⇒\sf{0.70x - 0.90x + 110 = 50}

Move 110 to right hand side and change it's sign

⇒\sf{0.70x - 0.90x = 50 - 110}

Collect like terms

⇒\sf{ - 0.2x = 50 - 110}

Calculate

⇒\sf{ - 0.2x =  - 60}

Divide both sides of the equation by -0.2

⇒\sf{ \frac{ - 0.2x}{ - 0.2}  =  \frac{ - 60}{ - 0.2} }

Calculate

⇒\sf{x = 300}

Hope I helped!

Best regards!!
