22
x = 22/7
154 = 22 x 7 = 14 + 140
2x - 7 = 15 2x = 22 x = 11
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
x-y = 6 -x-3y = 22 -4y = 28 y = -7 So by substituting: x = -1 and y = -7
22
2 x 22/7 = 44/7 or 6 2/7
x = 22/7
154 = 22 x 7 = 14 + 140
The ordered pair is (-1, -7).
2x - 7 = 15 2x = 22 x = 11
X +13 equals 22, X equals nine
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
1 x 2 + 22 = 6, 4 x 5 + 52 = 45, 3 x 6 + 62 = 54.... 72 = 7 x 2 + 22 = 18
x=-(29/11)
Is an equation of a straight line, with slope 7/3 x-intercept of 22/7 and y-intercept of -22/3
