Can someone explain this? I´m still confused 2 + 2y = –y − 10

2+2y=-y-10

2y+y=-10-2

3y=-12

y=-4

So y is the variable, so first step is isolating the variables meaning all the "y"s on one side of the equal sign and the numbers on the other side. After you isolate the variable, you can just do the addition/subtraction/multiplication/division.

Hope this helps!

infinitely many solutions

step-by-step explanation:

we have been given the equation;

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

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

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

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
