10x+140=130

10x=-10

x=-1

Answer 3

Let's solve each equation step by step:

a) 24 - (x + 2) = 13

To simplify the equation, we can remove the parentheses by distributing the negative sign:

24 - x - 2 = 13

Combine like terms:

22 - x = 13

Now, let's isolate the variable x by subtracting 22 from both sides:

• x = 13 - 22

Simplify:

• x = -9

To solve for x, we need to multiply both sides by -1 to eliminate the negative sign:

x = (-9) * (-1)

x = 9

So the solution to the equation is x = 9.

b) 10(x + 14) = 130

Let's simplify the equation by applying the distributive property:

10x + 140 = 130

Now, subtract 140 from both sides:

10x = 130 - 140

10x = -10

Divide both sides by 10 to solve for x:

x = -10/10

x = -1

Therefore, the solution to the equation is x = -1.
