Let's solve your system by substitution.
−3x+y=−2;y=4x
Rewrite equations:
y=4x;−3x+y=−2
Step: Solvey=4xfor y:
y=4x
Step: Substitute4xforyin−3x+y=−2:
−3x+y=−2
−3x+4x=−2
x=−2(Simplify both sides of the equation)
Step: Substitute−2forxiny=4x:
y=4x
y=(4)(−2)
y=−8(Simplify both sides of the equation)
Answer:
x=−2 and y=−8
x^3-10x^2=27x-18=0 has no solutions
x^3-10x^2-27x-18=0 has 3 solutions
x^3-10x^2-27x-18=0 also has three solutions

♡ The Explanation/Step-By-Step ♡
(3/4)^3
Apply Exponent Rule! --> (a/b)^c = a^c/b^c
(3/4)^3 = 3^3/4^3
3^3 = 27
= 27/4^3
4^3 = 64
= 27/64
27/64 = 0.421875
