Question

Раскрой скобки и приведи подобные слагаемые: 4(5z−3)+6z−9= *z .

Answer 1

20z-12+6z-9=14z-21 подобные 20z-6z и -12-9

Answer 2

I can help you with math problems. To solve this equation, you need to do the following steps:

1. Expand the brackets by multiplying 4 with each term inside: $$4(5z-3)+6z-9=z$$ 2. Simplify the expression by combining the like terms: $$20z-12+6z-9=z$$ 3. Subtract z from both sides to get all the z terms on one side: $$20z-12+6z-9-z=0$$ 4. Simplify again by combining the like terms: $$25z-21=0$$ 5. Add 21 to both sides to isolate z: $$25z=21$$ 6. Divide both sides by 25 to get the value of z: $$z=\frac{21}{25}$$

The final answer is $$z=\frac{21}{25}$$. I hope this helps.Ответь+подробно.+Раскрой+скобки+и+приведи+подобные+слагаемые:+4(5z−3)+6z−9=+*z+.
