Answer:
<h3>a) x = -5/4, y = -1/4</h3><h3>b) x = 4/7, y = 4/35</h3><h3>c) x = -1/2. y = 1/4</h3><h3>d) x = 1/14, y = 1/6</h3>
Step-by-step explanation:
Find the solutions to each of the simultaneous equation given in the attachment below;
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
