Answer:
Step-by-step explanation:
90x - 60y = 68.....multiply by -1
90x - 70y = 91
---------------------------
-90x + 60y = -68 (result of multiplying by -1)
90x - 70y = 91
---------------------------add
-10y = 23
y = -23/10 <===
90x - 60y = 68
90x - 60(-23/10) = 68
90x + 138 = 68
90x = 68 - 138
90x = - 70
x = -70/90
x = -7/9 <=====
Answer: It would be option B (13 over 5).
Step-by-step explanation: Step 1) Subtract 15 from both sides, 5x=13. Step 2) Divide both sides by 5, x=13 over 5. Hope this helps bub <3
