Question

140√x+315 =1015,then x is equal to _

Answer 1

140√x+315 =1015

Subtract 315 from both sides:

140√x =1015 - 315

140√x = 700

Divide both sides by 140:

√x = 700 ÷ 140

√x = 5

Square both sides:

x = (5)²

x = 25

Answer: x = 25

Answer 2

$140 \sqrt{x } + 315 = 1050 \\ 140 \sqrt{x} = 1050 - 315 \\ 140 \sqrt{x} = 700 \\ \sqrt{x} = 700 \div 140 \\ \sqrt{x} = 10 \div 2 \\ \sqrt{x } = 5 \\ x = 5 ^{2} \\ x = 25$
