17 = 7 + 8y
Subtract 7 from both sides:
10 = 8y
Divide both sides by 8:
10/8 = y
Simplify:
y = 5/4 or y = 1.25

What is x equals 6 and y equals 7 then 10x plus 8y?
10*6+8*7 = 116
How can you solve this elimination x plus 8y equals 3 2x plus 3y equals -7?
x + 8y = 3 therefore 2x + 16y = 6 (a) 2x + 3y = -7 (b) Subtract (b) from (a): 13y = 13 so y = 1 and x = -5
What is 2x plus 8y plus 7 equals 0?
2x = -7 - 8y
What is -8y - 7 equals -8 plus 8y?
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16

What is 5-11y-12 plus 8y equal?
(5 - 11y - 12) + 8y = 5 - 11y - 12 + 8y = ( - 7 - 3y )
What are the two numbers when a number plus thrice a number equals -4 and when thrice a number plus a number equals 44 showing work?
Let the numbers be x and y:- If: x+3y = -4 and 3x+y = 44 Then: 3x+9y = -12 and 3x+y = 44 Subtracting 3x+9y = -12 from 3x+y = 44: -8y = 56 => y = -7 By substitution: x = 17 and y = -7 Check: 17+3(-7) = -4 Check: 3(17) -7 = 44 Therefore the two numbers are: 17 and -7
