Question

110 +0.70x = 50+ 0.90x​

Answer 1

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

⇒$\sf{x = 300}$
