Answer:
x=-4 y=-1
Step-by-step explanation:
Let's solve your system by substitution.
−3x−8y=20;y=5x+19
Rewrite equations:
y=5x+19;−3x−8y=20
Step: Solve y=5x+19for y:
y=5x+19
Step: Substitute5x+19foryin−3x−8y=20:
−3x−8y=20
−3x−8(5x+19)=20
−43x−152=20(Simplify both sides of the equation)
−43x−152+152=20+152(Add 152 to both sides)
−43x=172
−43x
−43
=
172
−43
(Divide both sides by -43)
x=−4
Step: Substitute−4forxiny=5x+19:
y=5x+19
y=(5)(−4)+19
y=−1(Simplify both sides of the equation)
Answer:
x=−4 and y=−1

Answer:
X = 59
Step-by-step explanation:
2 × 59 = 118
18 + 18 + 59 + 59 = 154
F=95(K−273.15)+32
Switch the equation so that F is on the right side:
95(K−273.15)+32 = F
Use the distributive property:
95K + 95(-273.15) + 32 = F
95K - 25949.25 + 32 = F
95K - 25917.25 = F
Add 25917.25 to both sides:
95K = 25917.25 + F
Divide each term by 95:
K = 25917.25 / 95 + F/95
K = (25917.25 + F) /95
