k in (-oo:+oo) 2*k-(10/7)-7 = 8 // - 8 2*k-(10/7)-8-7 = 0 2*k-10/7-8-7 = 0 2*k-115/7 = 0 // + 115/7 2*k = 115/7 // : 2 k = 115/7/2 k = 115/14 k = 115/14

\[\frac{ 2k-10 }{ -7 } = 8\] What value do we need to be inserted over -7 to equal 8?

Yes, but you don't understand how this site works. Even if you do solve it step by step, you're supposed to give help, not answers.

It's ok. A good way to start helping someone is to ask: "What do you think?"

Then guide them from there, and show them how to get to the answer. :)

allright Step 1 : 10 Simplify —— -7
nikeboi101
  • nikeboi101
10 (2k - ——) + 8 -7
nikeboi101
  • nikeboi101
Step 2 : Rewriting the whole as an Equivalent Fraction :

k
nikeboi101
  • nikeboi101
Rewrite the whole as a fraction using -7 as the denominator : 2k 2k • -7 2k = —— = ——————— 1 -7
nikeboi101
  • nikeboi101
2k • 7 - (10 • -1) 14k + 10 —————————————————— = ———————— 7 7 Equation at the end of step 2 : (14k + 10) —————————— + 8 7

Step 3 : Rewriting the whole as an Equivalent Fraction : 3.1 Adding a whole to a fraction Rewrite the whole as a fraction using 7 as the denominator :
nikeboi101
  • nikeboi101
8 8 • 7 8 = — = ————— 1 7
nikeboi101
  • nikeboi101
Step 4 : Pulling out like terms :
nikeboi101
  • nikeboi101
14k + 10 = 2 • (7k + 5)

  • anonymous
10,-7
nikeboi101
  • nikeboi101
Adding fractions that have a common denominator : 4.2 Adding up the two equivalent fractions 2 • (7k+5) + 8 • 7 14k + 66 —————————————————— = ———————— 7 7
anonymous
  • anonymous
are the like terms right?
nikeboi101
  • nikeboi101
Step 5 : Pulling out like terms : 5.1 Pull out like factors : 14k + 66 = 2 • (7k + 33) Final result : 2 • (7k + 33) ————————————— 7
