Z+ 4 = 9 how can i do this plz explain and i would happily u

z+4=9

-4    -4

z= 5

you want to get the variable alone so you subtract 4 from both sides canceling out the 4. subtract 4 from 9 then you should get 5, after you divide the variable by 5. the answer is z=5

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
