Please help me solve question 2

sergiy2304 [10]

Answer:

solution: ( 3 , 6 )

$\sf y =6$

$\sf x =3$

Step-by-step explanation:

$\sf y = \frac{2}{3} x+4$

$\sf 2x+3y = 24$

make y the subject in equation 2:

$\sf 2x+3y = 24$

$\sf 3y = 24-2x$

$\sf y = \frac{24-2x}{3}$

insert this in equation 1:

$\sf \frac{24-2x}{3} =\frac{2}{3} x+4$

$\sf \sf \frac{24-2x}{3} =\frac{2x+12}{3}$

$\sf (24-2x) = (2x+12)$

$\sf -2x-2x=12-24$

$\sf -4x=-12$

$\sf x =3$

solve for y:

$\sf y = \frac{24-2x}{3}$

$\sf y = \frac{24-2(3)}{3}$

$\sf y =6$

Solve and check: 3 x2 + 5x + 6 + x − 1 x + 2 = 7 x + 3

vagabundo [1.1K]

Answer:

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

Step-by-step explanation:

Combine liked terms:

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

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

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

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

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

Now subtract 7x:

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

If you want combine liked terms:

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

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

Hope this helps!
