x + y = 10.
Substitute x = 4y into this equation: 4y + y = 10
Combine like ters: 5y = 10
Divide through by 5: y = 2
Substitute this value of y in x = 4y ie x = 4*2 = 8.

8x plus 4y equals 5 is 8x + 4y = 5.

How do you solve 4y plus x equals 8
Multiply the first equation by -3
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
4y + 10 = -18 4y = -28 y = -7
(2, -1)
4y+y=10 5y=10 y=2
8x plus 4y equals 5 is 8x + 4y = 5.
6y 10+4y subtract 4y from each side 2y 10 divide both sides by 2 y = 5

How do you solve 4y plus x equals 8
If y + 3y + 10 = 70, then 4y + 10 = 70, and 4y = 60. We then find that y = 60/4 = 15.
-4x + 4y = 1
Multiply the first equation by -3
6y = 10 + 4ySubtract 4y from each side:2y = 10Divide each side by 2:y = 5
