Its the last one I beleive not sure
Step-by-step explanation:
Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
<u>→Plug in 0 for y, into an equation:</u>
-4x - 0 = -28
-4x = -28
x = 7
A. There is one solution. The solution is where the lines intersect. Because both are linear and do not have the same slope, they will only cross once.
B. The solution is (3,4) since this is the coordinate at which the two lines intersect.
