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
Answer:
The answer is 9(7x – 1).
Step-by-step explanation:

Answer:
8−4 a
Step-by-step explanation:
x=g(h(a−4))
h(a−4)=−2(a−4)−5 = −2 a+8−5=3−2 a
Apply g.
g(h(a−4))=g(3−2a)=2(3-2a)+2=6−4a+2
