How many solutions does the equation 3x − 7 = 4 + 6 + 4x have
Sunny_sXe [5.5K]

Answer:

The given equation 3x − 7 = 4 + 6 + 4x has one solution.

Step-by-step explanation:

Given : Equation 3x − 7 = 4 + 6 + 4x

We have to find the number of solutions of the given equation.

Consider the given equation 3x − 7 = 4 + 6 + 4x

Simplify, we have,

3x − 7 = 10 + 4x

Now subtract 3x both side, we hvae,

-7 = 10 + 4x - 3x

Simplify, we have,

- 7 = 10 + x

Subtract 10 both side, we have,

-7 - 10 = x

x = - 17

Thus, The given equation 3x − 7 = 4 + 6 + 4x has one solution.

To solve the sustem of equations below, kira isolated variable y in the first equation then sybstituted it into the second equat
makvit [3.9K]

Answer:

Resulting equation is

x^2+\left(4x\right)^2=81

Step-by-step explanation:

Isolate y in the  first equation 3y=12x

divide both sides by 3

y=4x

Now we substitute this value of y into second equation

x^2+y^2=81

x^2+\left(4x\right)^2=81

Hence the resulting equation is

x^2+\left(4x\right)^2=81

Notice that question doesn't says to solve so there is no need to simplify or solve that equation further
