Question

What is x? 3x+43=100​

Answer 1

x= 19

Explanation:

3x+43= 100

Subtract 43 from both sides.

3x+43= 100

-43 -43

Then, divide 3 to both sides.

3x= 57

3 3

x= 19

Answer 2

x = 19

Explanation:

Solve for x:

3 x + 43 = 100

Subtract 43 from both sides:

3 x + (43 - 43) = 100 - 43

43 - 43 = 0:

3 x = 100 - 43

100 - 43 = 57:

3 x = 57

Divide both sides of 3 x = 57 by 3:

(3 x)/3 = 57/3

3/3 = 1:

x = 57/3

The gcd of 57 and 3 is 3, so 57/3 = (3×19)/(3×1) = 3/3×19 = 19:

Answer: x = 19
