Question

So

x+y=24
x=2y

I need step by step ple

Answer 1

y = 8

x = 16

Step-by-step explanation:

Given equations:

• x + y = 24
• x = 2y

Reorganize the equations:

`\left \{ {{x + y = 24} \atop {x = 2y}} \right.`

`\left \{ {{x + y = 24} \atop {x - 2y = 0}} \right.`

Subtract:

`\left \{ {{x + y = 24} \atop {x - 2y = 0}} \right.`

`{ {{[x - x] + [y - (-2y)]= 24 - 0}`

`{ {{x - x + y + 2y= 24}`

`3y= 24}`

Divide 3 both sides:

`(3y)/(3) = (24)/(3) }`

`y = 8`

Substitute y in any equation:

`x = 2(y)`

`x = 2(8) = 16`

Answer 2

• y = 8

• x = 16

Step-by-step explanation:

• x + y = 24

• x = 2(y)

solve, insert equation 2 into 1

• 2(y) + y = 24

• 3(y) = 24

• y = 8

Find x:

x = 2(y)

x = 2(8)

x = 16
