Then, you can check the income tax brackets here and do the math yourself

For 2024, you have 10% on $11,600 + 12% on ($47,150-$11,600) = 0.1 * $11,600 + 0.12 * $35,550 = $1,160 + $4,266 = $5,426. Then, you have 22% on all above the $47,150, which actually is $61,750 due to the deduction. Hence, it becomes

70,000 = x - 5,426 - 0.22*(x-61,750) = 0.78x + 8,159
61,841 = 0.78x
x = 79,283
