Step-by-step explanation:
please give full question
So multiply both sides by 5x to make 4/5x a whole number. So you get 4+5<-15x. So then simplifying you add 4 and 5. You get 9<-15x. So now divide both sides by -15 and switch the < to > because you’re multiplying by a negative. So then you get x<-9/15
Answer: x + 2y = 4
x - x + 2y = -x + 4
2y = -x + 4
2 2
y = ⁻¹/₂x + 2
Step-by-step explanation:
Multiply both sides by 17:
![-7 \cdot 17 = 11z](https://tex.z-dn.net/?f=%20-7%20%5Ccdot%2017%20%3D%2011z%20)
Evaluate the left hand side:
![-119 = 11z](https://tex.z-dn.net/?f=%20-119%20%3D%2011z%20)
Finally, divide both sides by 11:
![\displaystyle z = -\dfrac{119}{11}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20z%20%3D%20-%5Cdfrac%7B119%7D%7B11%7D%20)
