Can any anyone help me with this problem please Solve : 2x - 1 = 7

ziro4ka [17]

Answer:

$x = 4$

Step-by-step explanation:

Solve for $x$ :

$2x - 1 = 7$

-Add both sides by $1$ :

$2x - 1 + 1 = 7 + 1$

$2x = 8$

-Take $2x$ and divide it on both side of the equation:

$\frac{2x}{2} = \frac{8}{2}$

$x = 4$

So, the value of $x$ is $4$ .

Answer:

Step-by-step explanation:

A linear equation, when graphed, gives a straight line. This looks like you meant y=3x^3 - 3

There are parts of this equation that look like they could be linear, but the graph below shows that the graph does not go straight through -3. The graph therefore is non-linear.
