The expression -28x+35 is equivalent to 7y(-4x+5)
put both equations in standard form y - 3x = -5 (equation 1) -7y + 21x = 35 (equation 2) multiply equation 1 by 7 (this is done so either one of your variables will cancel... if both variables cancel then these lines are parallel) 7y - 21x = -35 -7y + 21x = 35 0 = 0 therefore your lines are parallel
It is: 5 to 2
56
5 x 7
The fraction 1 14/21 would be equivalent to 35/21.
1, 2, 5, 7, 10, 14, 35, 70, -1, -2, -5, -7, -10, -14, -35, -70
7(3x plus or minus 5) depending on the missing sign.
It is: 2/5
2/5, both can be divided by 7. 14/7=2, 35/7=5
Yeah
