5. 25 = x + 3

It is a one step equation. You just need to subtract 3 on both sides to get x.

6. 2b - 7 = 15

This is a two step equation. You need to add 7 on both sides and then divide both sides by 2 to get b.

7. 10m = 90

Finally, this is a one step equation. You need to divide both sides by 10 to find m.

What would the answer be for this equation 7x/20 - 5x/12
polet [3.4K]

Answer:

\frac{1}{15} x

Step-by-step explanation:

\frac{7x}{20}  -  \frac{5x}{12}

\frac{3 \times 7x}{3 \times 20}  -  \frac{5 \times 5x}{5 \times 12}

\frac{21x}{60}  -  \frac{25x}{60}

\frac{21x - 25x}{60}  = (21 - 25)x =  - 4x

\frac{ - 4x}{60}  =  -  \frac{ x}{15}

\boxed{\green{=  \frac{1}{15} x}}

Question Solve the equation. Check your solutions. ∣2x+1∣=∣3x−11∣
kirill [66]

Answer:

x=2 and x=12

Step-by-step explanation:

|2x+1| = |3x-11|

2x+1 = 3x-11

2x = 3x-12

-x = -12

x = 12

2x+1 = -(3x-11)

2x+1 = -3x+11

5x+1 = 11

5x = 10

x = 2
