A student provided the following solution for solving an equation What mistake did the student make? In the third line of the solution 3a should be
subtracted from each side instead of adding a to
each side
Original equation:
3(a - 2)+14 = 8-6
In the second line of the solution like terms were
combined incorrectly.
Solution: 3a - 2 + 14 =8-6a
3a + 12 = 8-60
9a + 128
9a --4
In the last line of the solution, the final answer
should be instead of -
4
9
In the first line of the solution, the distributive
property was applied incorrectly.

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

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
