solve the equation for x. show each step of the solution. name the justification for each step of the solution 9/2 (8-x) +36=102

Karo-lina-s [1.5K]

1. You have the following equation:

$\frac{9}{2}(8-x)+36=102-\frac{5}{2} (3x+24)$

2. First, you must apply the Distributive property:

$\frac{72}{2}-\frac{9x}{2}+36=102-\frac{15x}{2}-\frac{120}{2}$

3. Simplify:

$36}-\frac{9x}{2}+36=102-\frac{15x}{2}-60$

3. Add the like terms:

$-\frac{9x}{2}+\frac{15x}{2}=102-60-36-36\\ 3x=-30$

4. Solve for $x$ :

$x=-\frac{30}{3} \\ x=-10$

Therefore, the answer is: $x=-10$

Solve for x 5(x-10)=30-15x

timofeeve [1]

Answer:

solution :

x = 4

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*(x-10)-(30-15*x)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

5 • (x - 10) - (30 - 15x) = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

20x - 80 = 20 • (x - 4)

Equation at the end of step 3 :

20 • (x - 4) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 20 = 0
