Given the equation, 7x + 5 = 2(4x + 3):

Distribute 2 into the terms inside the parenthesis:

7x + 5 = 2(4x + 3)
7x + 5 = 8x + 6

Subtract 5 from both sides:

7x + 5 - 5 = 8x + 6 - 5

7x = 8x + 1

Then, subtract 8x from both sides:

7x - 8x = 8x + 1 - 8x

- x = 1

Finally, divide both sides by -1 to solve for x:

-x / -1 = 1 / -1

x = -1

Therefore, the solution to the given equation is -1.

Solve the following equation for x: 2x – 3y = 6.

Ksivusya [100]

Answer:

x=3/2y+3

Step-by-step explanation:

Let's solve for x.

2x−3y=6

Step 1: Add 3y to both sides.

2x−3y+3y=6+3y

2x=3y+6

Step 2: Divide both sides by 2.

2x2=3y+62

x=32y+3
