If 2x+y=8 and x+2=5. what is the value of y?​

y=2

Step-by-step explanation:

x+2=5

x= 5-2

x= 3

2x+y=8

2×3+y=8

6+y=8

y=8-6

y=2

y=2

Step-by-step explanation:

First solve x+2=5 to find x.

x+2=5

  -2  -2

x=3. Substitute x=3 into 2x+y=8.

(2 x 3) + y = 8

Now solve.

6 + y = 8

-6         -6

y=2.

Hope I helped x

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
