x = 12

Step-by-step explanation:

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

Add 7 on both sides to get rid of the 7 and isolate x.

$+7+2=\frac{3}{4}x-7+7$

$9=\frac{3}{4}x$

Now multiply both sides by $\frac{4}{3}$ to eliminate it and isolate x.

$(\frac{4}{3})(9)=(\frac{3}{4}x) (\frac{4}{3})$

12=x

Proof;

$2=\frac{3}{4}x-7\\2=\frac{3}{4}(12)-7\\2=9-7\\2=2$

Mathematics

x = 12

Step-by-step explanation:

2 = 3/4x - 7

2 + 7 = 3/4x

9 = 3/4x

9 × 4x = 3

36x = 3

x = 36/3

x = 12

no solution

Step-by-step explanation:

The equations describe parallel lines. There are no values of x and y that will satisfy both equations.

In standard form, the two equations are ...

3x +7y = 21

3x +7y = -42 . . . . . with positive leading coefficient

If (x, y) values satisfy the first equation, they cannot satisfy the second equation, and vice versa.

3x + 7y = 21 –3x – 7y = 42
