Answer 1

Answer:

you =46

Step-by-step explanation:

Replace all occurrences of yy in x−y=18x-y=18 with 0.5x+140.5x+14.

y=0.5x+14y=0.5x+14

x−(0.5x+14)=18x-(0.5x+14)=18

Simplify x−(0.5x+14)x-(0.5x+14).

y=0.5x+14y=0.5x+14

x−0.5x−14=18x-0.5x-14=18

Subtract 0.5x0.5x from xx.

y=0.5x+14y=0.5x+14

0.5x−14=180.5x-14=18

Solve for xx in the second equation.

Move all terms not containing xx to the right side of the equation.

Tap for fewer steps...

Add 1414 to both sides of the equation.

y=0.5x+14y=0.5x+14

0.5x=18+140.5x=18+14

Add 1818 and 1414.

y=0.5x+14y=0.5x+14

0.5x=320.5x=32

Divide each term by 0.50.5 and simplify.

Tap for fewer steps...

Divide each term in 0.5x=320.5x=32 by 0.50.5.

y=0.5x+14y=0.5x+14

0.5x0.5=320.50.5x0.5=320.5

Cancel the common factor of 0.50.5.

y=0.5x+14y=0.5x+14

x=320.5x=320.5

Divide 3232 by 0.50.5.

y=0.5x+14y=0.5x+14

x=64x=64
