Question

( 32 * 15 ) : 2 = ( \(x\) + 70 ) : 14 - 40

[61 + ( 53 - \(x\))] * 17 = 1785

\(x\) - 4867 = ( 175 * 2050 * 70 ) : 25 + 23

71 - ( 33 + \(x\) ) = 26

Answer 1

a) \(\left(32.15\right):2=\left(x+70\right):14-40\)

\(480:2=\left(x+70\right):14-40\\ 240+40=\left(x+70\right):14\\ 280=\left(x+70\right):14\\ x+70=3920\\ x=3850\)

b) \(\left[61+\left(53-x\right)\right].17=1785\)

\(61+\left(53-x\right)=105\\ 53-x=44\\ x=9\)

c) \(x-4867=\left(175.2050.70\right):25+23\)

\(x-4867=1004500+23\\ x-4867=1004523\\ x=1009390\)

d) \(71-\left(33+x\right)=26\)

\(33+x=45\\ x=12\)
