Answer 2

Answer:

10

Step-by-step explanation:

Solve for x:

7 x + 13 = 4 x + 43

Subtract 4 x from both sides:

(7 x - 4 x) + 13 = (4 x - 4 x) + 43

7 x - 4 x = 3 x:

3 x + 13 = (4 x - 4 x) + 43

4 x - 4 x = 0:

3 x + 13 = 43

Subtract 13 from both sides:

3 x + (13 - 13) = 43 - 13

13 - 13 = 0:

3 x = 43 - 13

43 - 13 = 30:

3 x = 30

Divide both sides of 3 x = 30 by 3:

(3 x)/3 = 30/3

3/3 = 1:

x = 30/3

The gcd of 30 and 3 is 3, so 30/3 = (3×10)/(3×1) = 3/3×10 = 10:

Answer:

x = 10
