Question

Y=2x-1 4x+3y=27 what is the value of y

Answer 1

y = 5, x = 3

Explanation:

`y=2x-1`

`4x+3y=27`

Substitute
`y=2x-1`

`[4x+3(2x-1)=27]`

Isolate x for
`4x+3(2x-1)=27`

`4x+3(2x-1)=27`

Expand
`3(2x-1)`

Apply the distributive law:
`a(b-c)=ab-ac`

`a=3,b=2x,c=1`

`=3*2x-3*1`

Simplify
`3*2x-3*1`

Multiply the numbers:
`3*2=6`

`=6x-3*1`

Multiply the numbers:
`3*1=3`

`=6x-3`

`4x+6x-3=27`

Add similar elements:
`4x+6x=10x`

`10x-3=27`

Add 3 to both sides

`10x-3+3=27+3`

Simplify

`10x=30`

Divide both sides by 10

`(10x)/(10) =(30)/(10)`

Simplify

`x=3`

For
`y=2x-1`

Substitute
`x=3`

`y=2*3-1`

`2*3-1`

Multiply the numbers:
`2*3=6`

`=6-1`

Subtract the numbers:
`6-1=5`

`=5`

`y=5`

Answer 2

The answer to your question is y = 5

Explanation:

Data

y = 2x - 1 Equation l

4x + 3y = 27 Equation ll

Process

1.- Substitute equation l in equation ll

4x + 3(2x - 1) = 27

2.- Expand

4x + 6x - 3 = 27

3.- Solve for x

10x = 27 + 3

10x = 30

x = 30/10

x= 3

4.- Substitute x in equation l

y = 2(3) - 1

y = 6 - 1

y = 5

5.- Solution

(3, 5)
