Answer:

X= 12

Step-by-step explanation:

Simplifying

4x + -2 = 46

Reorder the terms:

-2 + 4x = 46

Solving

-2 + 4x = 46

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 4x = 46 + 2

Combine like terms: -2 + 2 = 0

0 + 4x = 46 + 2

4x = 46 + 2

Combine like terms: 46 + 2 = 48

4x = 48

Divide each side by '4'.

x = 12

Simplifying

x = 12

mario62 [17]

Answer:

13) 7 + x/2 = 10

14)  2x - 5 = 7

15) 4x - 1 = 11

16) 6x - 6 = 12

17) x/3 + 10 = 12

18) 2x + 7 = 1

19) 9 + x/7 = 11

20) 8(n - 3)

Step-by-step explanation:

The quotient of x and 2 = x ÷ 2 = x/2

The product is the result of multiplying two or more other numbers

The sum is the result of adding two or more numbers

The difference is the result of subtracting one number from another

13) 7 + x/2 = 10

14)  2x - 5 = 7

15) 4x - 1 = 11

16) 6x - 6 = 12

17) x/3 + 10 = 12

18) 2x + 7 = 1

19) 9 + x/7 = 11

20) 8(n - 3)
