4x - 1<br> 2.<br> = x + 7<br> Can someone help please?

Answer:

6 $\frac{1}{3}$

Step-by-step explanation:

4x-12 = x+7

4x-12+12 = x+7+12

4x = x+19

4x-x = x+19-x

3x=19

x = 6 $\frac{1}{3}$

And if we substitute the value of x into the equation 4x-12 = x+7,

we will get 13 $\frac{1}{3}$ = 13 $\frac{1}{3}$ in the end.

Hope this helps :)

Can someone pls help me on this I dont understand this

Zielflug [23.3K]

Answer:

3rd option

Step-by-step explanation:

The equation of a line in point- slope form is

y - y₁ = m(x - x₁)

where m is the slope and (x₁, y₁ ) a point on the line

Here m = - 2 and (x₁, y₁ ) = 4. - 6 ) , then

y - (- 6) = - 2(x - 4) , that is

y + 6 = - 2(x - 4)
