6x + 18 = 54
6x = 54 - 18
6x = 36
x = 36 ÷6
x = 6
5/8
Solving by the elimination method: x = 7 and y = 2
9x + 3y = -54 3y = -9x - 54 y = -(3x + 18) Therefore, the y-intercept of this equation is y=-18.
54 + 560 + 90 = 704
51/54 equals 17/18

Solving by the elimination method: x = 7 and y = 2
18 + 18 + 18 = 54
4x + 4 + 14 = 54 4x + 18 = 54 4x = 54 - 18 4x = 36 x = 36/4 x = 9 Check: 4(9) + 4 + 14 = 54 36 + 18 = 54 54 = 54
54 divided by 3 equals 18 Check: 18 + 18 = 36 36 + 18 = 54
It is: 126 plus 54 = 180
9x + 3y = -54 3y = -9x - 54 y = -(3x + 18) Therefore, the y-intercept of this equation is y=-18.
54 + 560 + 90 = 704
The lowest common multiple of 18 and 54 is 108. 54 times 2 equals 108, and 18 times 6 equals 108.
18 time 3 equals 54
51/54 equals 17/18
