How many solutions? y = 5(x – 4) 4x + 12 = -y

Mathematics
1 answer:
kakasveta [241]3 years ago
4 0

Answer:

One solution, x = 8/9

Step-by-step explanation:

One way to solve this is to take one equation and substitute into the other and then solve. So, take y=5(x-4) and put that into the other equation.

4x + 12 = -y

4x + 12 = -(5(x-4))       <--- substitution here

4x + 12 = -5(x-4)

4x + 12 = -5x + 20     <-- simplifying

4x + 5x = 20 - 12

9x = 8

x = 8/9

Given -3(2x+7)=-29-4x prove x=4
Doss [256]

Answer:

x = 4

Step-by-step explanation:

Given

- 3(2x + 7) = - 29 - 4x ← distribute parenthesis on left side

- 6x - 21 = - 29 - 4x ( add 4x to both sides )

- 2x - 21 = - 29 ( add 21 to both sides )

- 2x = - 8 ( divide both sides by - 2 )

x = 4 ← as required

2 13/18 −z=1 19/36 <br><br>Answer
allsm [11]

Answer:

Answer is z= 43/36

Step-by-step explanation:

We have given,

2 13/18 - z = 1 19/36

Since 2 13/18 = 49/18  and 1 19/36 = 55/36

So we can write,

2 13/18 - z = 1 19/36

or 49/18 - z = 55/36

or 49/18 - 55/36 = z

or (98 -55)/36 = z

or 43/36 = z

Hence we got z = 43/36
