Question

30+(14-х)=40 7*х=32+38

Answer 1

$1) 30 + (14 - x) = 40\\14 - x = 40 - 30\\14 - x = 10\\x = 14 - 10\\x = 4\\\\2)7 * x = 32 + 38\\7 * x = 70\\x = 70 : 7\\x = 10$

Answer 2

To solve the equations, let's go step by step:

1. Equation 1: 30 + (14 - x) = 40

First, simplify the expression inside the parentheses:

30 + (14 - x) = 40 30 + 14 - x = 40 44 - x = 40

Now, isolate the variable x by subtracting 44 from both sides:

44 - x = 40 44 - 44 - x = 40 - 44 -x = -4

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

-x = -4 (-1)(-x) = (-1)(-4) x = 4

Therefore, the solution for Equation 1 is x = 4.

2. Equation 2: 7 * x = 32 + 38

First, simplify the right side of the equation:

7 * x = 32 + 38 7 * x = 70

Now, divide both sides by 7 to solve for x:

(7 * x) / 7 = 70 / 7 x = 10

Therefore, the solution for Equation 2 is x = 10.

In summary, the solutions for the given equations are: Equation 1: x = 4 Equation 2: x = 10
