I need help on this question

  -7/30

Step-by-step explanation:

You can use 30 as the common denominator.

  7/10 = (7/10)(3/3) = 21/30

  14/15 = (14/15)(2/2) = 28/30

Then the difference is ...

  7/10 -14/15 = 21/30 -28/30

  = (21-28)/30 = -7/30

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
