Solve and check: 3 x2 + 5x + 6 + x − 1 x + 2 = 7 x + 3
vagabundo [1.1K]

Answer:

3x^{2} -2x +5=0

Step-by-step explanation:

Combine liked terms:

3x^{2}+5x+x-1x+6+2=7x+3

3x^{2}+6x-1x+8=7x+3

3x^{2}+5x+8=7x+3

Subtract 3: 3x^{2}+5x+8-3=7x+3-3

3x^{2}+5x+5=7x

Now subtract 7x:

3x^{2}+5x+5-7x=7x-7x

If you want combine liked terms:

3x^{2}-7x+5x+5=0

3x^{2}-2x+5=0

Hope this helps!

John has × marbles and max has twice as many.max give gives john 5 of his marbles does max now have
rjkz [21]

Answer: 2x -5

Step-by-step explanation:

Hi, to answer this question we have to write equations with the information given:

  • <em>John has × marbles  </em>

John=x

  • <em>Max has twice (multiplied by 2) as many.max give gives john 5 of his marbles. </em>

We have to multiply by 2 the number of marbles that John has (x), and subtract 5.  

Max = 2x -5

Feel free to ask for more if needed or if you did not understand something.
