2)3-1/7х)-4=1/4х

Answer 2

It seems like you have two linear equations that you'd like to solve for x. Let's solve them step by step:

1. $2 - \frac{2}{3}x = 5$

First, we can isolate the term with x on one side of the equation by moving the constant term to the other side:

$2 - 5 = \frac{2}{3}x$

Now, subtract 2 from 5:

$-3 = \frac{2}{3}x$

Next, to solve for x, multiply both sides by $\frac{3}{2}$ (the reciprocal of $\frac{2}{3}$):

$\frac{-3}{1} \cdot \frac{3}{2} = \frac{2}{3}x \cdot \frac{3}{2}$

Simplify:

$-\frac{9}{2} = x$

So, the solution to the first equation is $x = -\frac{9}{2}$.

2. $3 - \frac{1}{7}x - 4 = 0$

First, simplify the equation by combining like terms:

$-1 - \frac{1}{7}x = 0$

Now, add 1 to both sides to isolate the term with x:

$-1 + 1 - \frac{1}{7}x = 0 + 1$

$-\frac{1}{7}x = 1$

To solve for x, multiply both sides by $-7$ (the reciprocal of $-\frac{1}{7}$):

$-\frac{1}{7}x \cdot (-7) = 1 \cdot (-7)$

Simplify:

$x = -7$

So, the solution to the second equation is $x = -7$.

Therefore, the solutions to the two equations are:

1. $x = -\frac{9}{2}$

2. $x = -7$
