Question

Escreva as equações do 1° grau na forma reduzida: a) 3× - 5 = 2y b) -24y + 3 = 1 - × c) 11 - y = -7× d) 6× + 2 = y + ×

Answer 1

a) 3× - 5 = 2y ==> y = (3× - 5)/2
b) -24y + 3 = 1 - ×==> -24y  = 1 - × - 3 ==> -24y = - 2 - x(-1)
24y =2 +x ==> y = ( 2 + x)/24
c) 11 - y = -7× ==> y = 11 + 7x
d) 6× + 2 = y + × ==>  y =  6x - x + 2 ==> y = 5x + 2
