4(3y-1)+13=5y+2 please help me

y is equal to -1.

Step-by-step explanation:

4(3y - 1) + 13 = 5y + 2

12y - 4 + 13 = 5y + 2

12y + 9 = 5y + 2

      - 2         -  2

12y + 7 = 5y

-12y         -12y      

=                

-1 = y

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

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
