What is the equivalent −51−(−60)

9

Step-by-step explanation:

Based on the algebraic rules for subtracting negative numbers,

when you subtract a negative number, the two negative signs cancel out and instead becomes an addition sign.

For example:

a - -b = a+b

-a - -b = -a + b

Therefore, following this rule,

the equation -51-(-60)

will change the -(-60) into a +60, so

-51 + 60

60-51 = 9

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
