( x + 340 ) - 152 = 214
x + 340 - 152 = 214
x + 188 = 214
x = 214 - 188
x = 26
( 26 + 340 ) - 152 = 214
800 : y - 300 = 500
800 : y = 500 + 300
800 : y = 800
y = 800 : 800
y = 1
800 : 1 - 300 = 500
500 + ( x + 140 ) = 2 056
x + 140 = 2 056 - 500
x + 140 = 1 556
x = 1556 - 140
x = 1416
500 + ( 1416 + 140 ) = 2 056
( a + 200 ) : 400 = 2
a + 200 = 400 • 2
a + 200 = 800
a = 800 - 200
a = 600
( 600 + 200 ) : 400 = 2
