none of the answers are correct . . are you sure you wrote the equation out correctly. Please check your problem to ensure you wrote everything correctly.
Otherwise, the equation is calculated as such
2x=4y-50 then insert the y value of 1-5x into the first equation
2x=4(1-5x)-50 then multiply...
1/4(x+1/2)- 2/3(x-1/6)- ½
Rearrange to combine the x’s and the numbers to make it easier to add and subtract
1/4x-2/3x+1/8+1/9(this is 2/18 reduced)-1/2
You must find a common denominator before you can add or subtract, so the common denominator for the x variable...
1.42984 X 10^8
usually you want to have it in this form, where you have one number and then a decimal followed by the rest of the numbers.
Add 39 to both sides
Then subtract 28m from both sides
Then divide both sides by -2
2x+2y=38 x=5+y insert the value of x into the first equation 2(5+y)+2y=38 10+2y+2y=38 4y=28 y=7 Now, insert the value of y into the second equation x=5+y x=5+7 x=12 so the length is 12 and the width is 7
