Work Step by Step

given x =7, y= 5 evaluate $\frac{2y- x+24}{2x-y}$ Step 1: Substitute the value of x =7 and y=5 in the given expression According to the order of operations perform multiplication $\frac{2*5- 7+24}{2*7-5}$ $\frac{10- 7+24}{14 - 5}$ Step 2: Now perform addition $\frac{34 - 7}{14 -5}$ Step 3: perform subtraction $\frac{27}{9}$ Step 4: simplify by dividing 27 by 9 $\frac{27}{9}$ = 3
