Start by combing like terms. You will get 3x+12=51. Now subtract 12 from both sides (3x=39). Divide both sides by 3 (x=13). The answer is 13.
Answer:
<h2>
(-3,8)</h2><h2>
Or</h2><h2>
x=-3 and y=8</h2>
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
It's a parallel line so the equation is
100+19x+4=180
19x=180-100-4
19x=76
x=76/19
x=4
Answer:
1E-6 m^3 or 0.000001 m^3
Step-by-step explanation:
1cm^3 = 1cm*1cm*1cm
1m^3 = 100cm*100cm*100cm = 1000000 cm^3
1/1000000 = 1E-6 m^3

hello :
<span>help :
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x =
(-b±√Δ)/2a</span>
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions</span>
