What is solution for the following system of equations, 2x+8y=4 and x=-3y+5
1 answer:
Answer:
1) x=14 and y=-3
Step-by-step explanation:
To solve the system of equations, substitute x = -3y+5 into the equation 2x + 8y = 4 for x. This becomes 2(-3y+5) +8y = 4. To solve, apply the distributive property, combine like terms and isolate y.
2(-3y+5)+8y=4
-6y+10+8y=4
10+2y=4
10-10+2y=4-10
2y=-6
y=-3
Then to find x, substitute y =-3 into x =-3y+5.
x = -3(-3) + 5
x = 9 + 5
x = 14

Step-by-step explanation:
0,2,3,4,5,6,7,8
There are 8 options, 3 of which are greater than 5
3/8
3/8 = x/150
3*150 = 450
8 * x = 8x
8x = 450
450/8 = 56.25
