<h3>
answer:</h3>
x = 5
y = -4
<h3>
steps:</h3>
4x + y = 16
multiply 2nd equation by 2
4x + 6y = -4
subtract equations
0 -5y = 20
-5y = 20
y = 20 ÷ -5
y = -4
substitute y = -4 to find the value of x
4x + (-4) = 16
4x - 4 = 16
4x = 20
x = 5
Answer:
n = 7
Step-by-step explanation:
1 = -6 + n
1 + 6 = n
7 = n
n = 7
Answer:
Step-by-step explanation:
First, graph the "equals" line, then shade in the correct area.
There are three steps:
1) Rearrange the equation so "y" is on the left and everything else on the right.
2) Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
3) Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).
hope this helpled :)
Answer:
it would be c when fully simplified.
