If x = 7 you substitute all the x in the equation by 7:
y = -2(7) + 5
y = -14 + 5
y = -9
Hope it helped,
Happy homework/ study/ exam!
Answer: is it for math
Step-by-step explanation:
A. 12*x + 2*y = 90
6*x + 2*y = 60
To write system of equation you just need to sum all solo and ensemble acts and make it equal to how much they will last for.
B. Here we can multiply second equation with negative 1 and add it to first equation.
6x = 30
x = 5
now we replace x in any of 2 equations to get y.
30+2y = 60
2y = 30
y=15
Solo acts are 5 minutes long and ensemble acts are 15 minutes long
