In second equation add 0.74 and y to both sides: 3.25x+0.74=y;
Substitute y in the first equation: -4.5x-2(3.25x+0.74)=-12.5;
Distribute multiplication over addition:
-4.5x-6.50x -1.48=-12.5;
Combine like terms and add 1.48 to both sides:
-11x= -12.5+1.48;
-11x= 11.02 divide both sides by -11;
X= -11.02/11= -1.00(18)
Y= 3.25• -1.00(18)+.74= -2.515(90)
Answer:
x∈ (-1, ∞)
Step-by-step explanation:
<u>Solution of the inequality:</u>
- −2(3x − 1) < 8 ⇒ Divide both sides by -2, this will change inequality
sign to opposite
- 3x - 1 > -4 ⇒ add 1 to both sides
- 3x > -3 ⇒ divide both sides by 3
- x > -1 ⇒ answer
- x∈ (-1, ∞) ⇒ answer as set
There not a answer for that
