-3q + 12 greater than equal too 4q - 30 solve for q

Answers

Solving the inequality -3q+12\geq 4q-30 the value of q is q\leq 6

Step-by-step explanation:

We need to solve the inequality: -3q+12\geq 4q-30 and find value of q

Solving:

-3q+12\geq 4q-30\nAdding\,\,-12\,\,on\,\,both\,\,sides:\n-3q+12-12\geq 4q-30-12\n-3q\geq 4q-42\nAdding\,\,-4q\,\,on\,\,both\,\,sides:\n-3q-4q\geq 4q-42-4q\n-7q\geq -42\nDivide\,\,both\,\,sides\,\,by\,\,7\n(-7q)/(7)\geq (-42)/(7)\n -q\geq -6\nMultiply\,\,both\,\,sides\,\,by\,\,-1\,\,and\,\,reverse\,\,the\,\,inequality:\nq\leq 6

So, solving the inequality -3q+12\geq 4q-30 the value of q is q\leq 6
