Complete the solution of the equation. find the value of y when x equals -20. x+3y=7

9

Step-by-step explanation:

-20+3y=7

3y=27

y=9

y=9

Step-by-step explanation:

replace all x with -20:

3y-20=7

Move the -20 to the other side by adding 20 on both sides:

3y-20+20=7+20

Simplify:

y=9

Hope this helps!

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
