Solve equation 19 - h - h = -13

h = 16

Step-by-step explanation:

to solve this equation

we are going to take cognizance of the positive and negative sign as any misinterpretation of the sign might influence our answer wrongly. Note this

negative × negative  = positive

positive × negative = negative

negative × positive = negative

positive × positive = positive

so, from the question 19 - h - h = -13

19 - h - h = -13

19 -2h = -13

collect the like terms

19 + 13 = 2h

32 = 2h

divide both sides by the coefficient of h which is 2

32/2 = 2h/2

16 = h

therefore h = 16

answer: t=3
