0.5x+7/3 = 21/4 cross multiply

TiliK225 [7]

Solving the expression $\frac{0.5x+7}{3}=\frac{21}{4}$ we get: $x=\frac{35}{2}\,\,or\,\,x=17.5$

Step-by-step explanation:

Solving the expression: $\frac{0.5x+7}{3}=\frac{21}{4}$

Solving by cross multiplying:

$\frac{0.5x+7}{3}=\frac{21}{4}\\(0.5x+7)*4=21*3\\Simplifying:\\2x+28=63\\Adding\,\,-28\,\,on\,\,both\,\,sides:\\2x+28-28=63-28\\2x=35\\Divide\,\,both\,\,sides\,\,by\,\,2\\\frac{2x}{2}=\frac{35}{2}\\x=\frac{35}{2}\,\,or\,\,x=17.5$

So, solving the expression $\frac{0.5x+7}{3}=\frac{21}{4}$ we get: $x=\frac{35}{2}\,\,or\,\,x=17.5$
