Answer:

x = 11

Step-by-step explanation:

sqrt (2x - 5) = sqrt (x + 6)

Square both sides

2x - 5 = x + 6

x = 11

Verify:

sqrt[2(11) - 5] = sqrt(11 + 6)

sqrt(17) = sqrt(17)

Answer:

x = 11

Step-by-step explanation:

√2x-5 - √x+6 = 0

√2x-5 = √x+6

(√2x-5)² = (√x+6)²

2x - 5 = x + 6

2x - x = 6 + 5

x = 11

Alona [7]

Answer:

x = 72

Step-by-step explanation:

$9 + \frac{3}{4} x = \frac{7}{8} x - 10 \\ \frac{3}{4}x - \frac{7}{8} x = - 10 - 9 \\ \frac{6}{8} x - \frac{7}{8} x = - 19 \\ - \frac{1}{8}x = - 19 \\ x = \frac{ - 9}{ - \frac{1}{8} } \\ x = 72$
