Answer: x = 13
Step-by-step explanation:
7 more = + 7
twice a number = 2*x = 2x
6 less = -6
3 times the same number = 3 * x = 3x
Putting this together we get:
2x + 7 = 3x - 6
subtract two from both sides to isolate x
(-2x) + 2x + 7 = 3x - 6 (-2x)
7 = x - 6
add 6 to both sides to get your answer
7 (+6) = x - 6 (+6)
13 = x
or
x = 13
