Ecuaciòn lineal en una varible

Answer 1

x = 2     8x = 8 ( 2 ) = 16

x = 8     25 - 4x = 25 - 4(8) = 25 - 32 = - 7

x = - 1     3x - 5 = 3( -1 ) - 5 = - 3 - 5 = - 8

y = - 1     5y + 8 ( y - 2 ) = 5 ( - 1 ) + 8 ( - 1 - 2 ) = - 5 + 8 ( - 3 ) = - 5 - 24 = - 29

x  = 10     2/5x - 15x + 3 = 2(10)/5 -15(10) + 3 = 4 - 150 + 3 = - 143

x = - 14     3/7x - x = 3(-14)/7 - ( - 14 ) = - 6 + 14 = + 8

x = 4     25 + 8x - 3(x - 12) = 25 + 8(4)-3(4-12) = 25+32+24 = 81

s = 3/5     1/2 + 6s = 1/2 + 6 ( 3/5) = 1/2 + 18/5 = 5/10 + 36/10 = 41/10

z = - 3     -2( 13z +1) +7(z+5) = -2( 13(-3) + 1 ) + 7(-3+5) = - 2(-39+1)+7(2) = 76 + 14 = 90

q = - 1/3     - 12q - 9 = -12( -1/3 ) - 9 = 12/3 -9 = 4 - 9 = - 5
