x + 13x + 10x = 50 - 6
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
-6x-6 -or- -6(x+1)
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
x + 13x + 10x = 50 - 6
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
-6x-6 -or- -6(x+1)
y=-10x-4
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
-6
10*6+8*7 = 116
Substitute the values of x and y in 10x + 7y, thus: 10x + 7y = 10*9 + 7*6 = 90 + 42 = 132
10x + 2 - 62 Subtract '2' from both sides 10x = 60 Divide both sides by '10'/ x = 6 The answer!!!!!
5=4x 1.25=x
x = 6 and 2/7
