Answer:
x=4,y=−2
Step-by-step explanation:
1 Solve for x in -2y+x=8
x=8+2y
2 Substitute x=8+2y into 3y+2x=2
7y+16=2
3 Solve for y in 7y+16=2
y=-2
4 Substitute y=-2 into x=8+2y
x=4
5 Therefore,
x=4
y=−2
Answer:
f(-5) = 19
Step-by-step explanation:
Missing and incorrect;
f(x) = −3x + 4
x = −5
Find:
Solution of f(x)
Computation:
f(x) = −3x + 4
f(-5) = −3(-5) + 4
f(-5) = 15 + 4
f(-5) = 19
