Answer:

x = 8

Step-by-step explanation:

3/4x - 7 = -1

Your first step is to isolate the variable term 3/4x, to do this you have to add 7 to both sides:

3/4x -7 (+7) = -1 (+7)

3/4x = 6

Next, you want to get rid of the fraction by multiplying both sides by the denominator #, 4

3/4(x4) x = 6(x4)

3x = 24

Final step, you divide by three to isolate the x!

3x/3 = 24/3

x = 8

Hope this helps! =D

Step-by-step explanation:      

Step 1: Add 7 to both sides.

[tex]\frac{3}{4}x-7+7=-1+7[/tex]

Step 2: Simplify

[tex]\frac{3}{4}x=6[/tex]

Step 3:  Multiply both sides by 4

[tex]4\cdot \frac{3}{4}x=6\cdot \:4[/tex]

Step 4: Simplify

[tex]3x=24[/tex]

Step 5: Divide both sides by 3

[tex]\frac{3x}{3}=\frac{24}{3}[/tex]

Step 6: Simplify

[tex]x=8[/tex]

Explanation in words (Short Form)

-  The first step is to add 7 to both sides and the answer will result as 3/4x=6.

- The second step is to multiply both sides by 4/3 and the final answer will result as x = 8.

Answer:    

[tex]x=8[/tex]
