Equivalent fractions for 1/4
From this chart, we can observe that the equivalent fractions of 1/4 are: 2/8, 3/12, 4/16,... Two fractions are said to be equivalent if their values (decimal/graphical) are the same. We usually multiply the numerator and denominator of a fraction by the same number to get its equivalent fraction.
4(x+8)-4=34-2x steps
4x + 32 - 4 = 34 - 2x
4x + 28 = 34 - 2x
4 x + 2 x = 34 - 28
6 x = 6
x = 6/6
x = 1
Since y=7x we can replace the y in the second equation with 7x
-5x+14x=9
x=1
Now plug in to get 7 for y, since 7x=y
Answer: x=1, y=7
