If x + y = 10 and y = x + 8
Substitute y = x + 8 into x + y = 10
Which gives; x + x + 8 = 10
So; 2x + 8 = 10
( - 8 from both sides); 2x=2
So: x =1. Substitute back into y = x + 8
And therefore y = 1 + 8 ; y=9
How do you solve 4y plus x equals 8
x = -8
5
2x+8=10... Subtract 8 on both sides, then devide by 2... 2x=2... x=1
8+2=10 6-2=4
How do you solve 4y plus x equals 8
x = -8
x=-8

8
2x+8=10... Subtract 8 on both sides, then devide by 2... 2x=2... x=1
8+2=10 6-2=4
8x2 + 16x + 8 = 0
-2
32 divided by 4 equals 8 plus 4 equals 12 multipled by 8 equals 96 answer
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
