Answer:

1. x = 8

2. x = 12

3. x = 11

4. x = 6

Step-by-step explanation:

102 + 102 = 204

360 - 204 = 156

156 / 2 = 78

78 = 10x - 2

78 + 2 = 10x

80 = 10x

80 / 10 = x

x = 8

81 = 7x - 3

81 + 3 = 7x

84 = 7x

84 / 7 = x

x = 12

77 = 6x + 11

77 - 11 = 6x

66 = 6x

66 / 6 = x

x = 11

115 + 115 = 230

360 - 230 = 130

130 / 2 = 65

65 = 8x + 17

65 - 17 = 8x

48 = 8x

48 / 8 = x

x = 6

Solve this equation using elimination: 4x-y=8;6x+y=2

fomenos

Solve simultaneously.

4x - y = 8
6x + y = 2

Multiply top equation by 6, and bottom equation by 4, to eliminate x, so that we can find y.
~
24x - 6y = 48
24x - 4y = 8

Subtract top from bottom to form one equation.
~
-2y = 40
Therefore y is 20.

Put y back in to an equation, such as 4x - y = 8.
~
4x - 20 = 8
4x = 28
x = 7
