Step-by-Step Solution

Let's solve the linear equation 6+3(x+4)=73(x2) 6 + 3(x + 4) = 7 - 3(x - 2) step-by-step.

Step 1: Expand the terms using the distributive property.

On the left side: 3(x+4)=3x+12 3(x + 4) = 3x + 12

On the right side: 3(x2)=3x+6 -3(x - 2) = -3x + 6

Substituting back, the equation becomes:

6+3x+12=73x+6 6 + 3x + 12 = 7 - 3x + 6

Step 2: Simplify both sides by combining like terms.

Left side: 6+12+3x=18+3x 6 + 12 + 3x = 18 + 3x

Right side: 7+63x=133x 7 + 6 - 3x = 13 - 3x

The equation now is:

18+3x=133x 18 + 3x = 13 - 3x

Step 3: Bring all terms involving x x to one side.

Add 3x 3x to both sides:

18+3x+3x=13 18 + 3x + 3x = 13

18+6x=13 18 + 6x = 13

Step 4: Isolate the variable x x .

Subtract 18 from both sides:

6x=1318 6x = 13 - 18

6x=5 6x = -5

Divide both sides by 6:

x=56 x = -\frac{5}{6}

Therefore, the solution to the problem is x=56 x = -\frac{5}{6} .

Answer

56 -\frac{5}{6}
