Explanation

Start with the equation:

3x−7=11

Add 7 to both sides to isolate the term with x:

3x−7+7=11+7

3x=18

Divide both sides by 3 to solve for x:

3𝑥/ 3 = 18/3

​x=6

Explanation

To solve the equation  5x−7=3x+5:

1: Start by isolating x on one side of the equation

5x−7=3x+5

2: Subtract 3x from both sides:

5x−3x−7=5

2x−7=5

3: Add 7 to both sides:

Explanation

To find the length of one side of a square given the perimeter,

you can use the formula for the perimeter of a square:

Perimeter=4×side length

Given that the perimeter is 40 cm, set up the equation:

40=4×side length

To find the side length, divide both sides by 4:

side length= 40/4=10 cm

Explanation

To find the original price before the 20% increase, follow these steps:

1. Let the original price be  P. The price is increased by 20%, so the new price is 120% of the original price.

New Price=1.20×Original Price

2. Set up the equation using the given new price of $60:

1.20×P=60

3. Solve for 

 𝑃= 60/ 1.20 = 50

So, the original price was $50. 

Explanation

The expression appears to be $2(x + 4)$.

Let's solve it for $x = -3$:

Substitute 

$x = -3$ into the expression: $$2(x + 4) = 2(-3 + 4) = 2(1) = 2$$
