Tom bought a soft drink for four dollars and seven candy bars. he spent a total of thirty- nine dollars. how much did each candy bar cost

ans:5 dollars

soft drink=4 dollars

39 dollars=a soft drink + seven candy bars

39=4+7candy

7candy=35

each candy=5 dollars

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

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
