∙ 9y agox + y = 1
therefore x = 1 - y.
2x - y = -2
substituting x = 1 - y in this equation gives 2*(1 - y) - y = -2
That is, 2 - 2y - y = -2
or -3y = -4 => y = 4/3.
Then x = 1 - y => x = 1 - 4/3 = -1/3.
Therefore, the solution is (x, y) = (-1/3, 4/3).

∙ 9y agoTo solve the system of equations using the substitution method:
2x-3y=13
how do you use the substitution method for this problem 2x-3y=-2 4x+y=24
If: x+y = 4 and y = 2x+1 Then: 4-x = 2x+1 => 3 = 3x => 1 = x So by substitution: x = 1 and y = 3
-2
This is not Calculus.y=7(Already solved)substiute y=7 into y=8xtherefore 7 = 8xtherefore x = 7/8

(2,3)
If: x+y = 4 and y = 2x+1 Then: 4-x = 2x+1 => 3 = 3x => 1 = x So by substitution: x = 1 and y = 3
-2
Substitution method: y = 1 + x so 2x + (1 + x) = 4, ie 3x = 3 so x = 1 and y = 2
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
This is not Calculus.y=7(Already solved)substiute y=7 into y=8xtherefore 7 = 8xtherefore x = 7/8
Substitution property.
