-8= 3-5(x+6) solving algebraicaily​
SOVA2 [1]

Let's solve your equation step by step

-8=3-5(x+6)

Step 1: simplify both sides of the equation

-8=3-5(x+6)

-8=3+(-5)(x)+(-5(6) (distribute)

-8=3+-5x+-30

-8=(-5x)+(3+-30) (combine like terms)

-8=-5x+-27

-8=-5x-27

Step 2: flip the equation

-5x-27=-8

Step 3: add 27 to both sides

-5x-27+27=-8+27

-5x=19

Step 4: Divide both sides by -5

-5x/-5 = 19/-5

Answer : x= -19/5

"in a school, 25% of the teachers teach basic math. If there are 50 basic math teachers, how many are there in the school? "
AveGali [126]
The answer is 200.

The reason is because if you have 50 teachers, and that is 1/4 of the number of total teachers, then you would multiply the number of basic math teachers by four.
