What’s seven fives/ ninths subtract 3 2/15

answer:

4 19/45

step-by-step explanation:

subtract wole number 7-3=4

combine fractions

5/9-2/19=19/15

=25/45 - 6/45

= 25-6/45

= 19/ 45

=4+ 19/45

4 19/45

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
