Can anyone become my math tutor please?

4x + 2x − 7 = 3x − 7

3x=0 or x=0

Step-by-step explanation:

4x+2x-7=3x-7

4x+2x=3x

6x=3x

6x-3x=0

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

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
