Answer:
What do you mean? 14+17 is 31.. 14<17
Answer:
1. x = 2 y = 1
2. x = 17 y = 29/3
Step-by-step explanation:
1. Use elimination
-4x+3y=-5
4x-5y=3
x's cancel, so add them
-2y = -2
y = 1
substitute
4x -5(1) = 3
4x - 5 = 3
4x = 8
x = 2
2. Use elimination
2x+3y=36
10x-6y=12
Multiply top equasion by 5
10x+30y = 360
10x-6y = 12
x's cancel so subract
36y = 348
y = 29/3
Substitute
2x+3(2/3)=36
2x+2 = 36
2x = 34
x = 17
Answer:
28
Step-by-step explanation:
Substitute 7 for x in the given equation
-3(x + 4) + 15 = 6 - 4x......distribute the -3 thru the parenthesis
-3x - 12 + 15 = 6 - 4x....simplify
-3x + 3 = 6 - 4x...add 4x to both sides
-3x + 4x + 3 = 6....subtract 3 from both sides
-3x + 4x = 6 - 3....simplify
x = 3 <==
Step-by-step explanation:
an = -9 + 7(n-1)
because you start at -9 and go up by increments of 7
