Answer:
x=2, y = -1
Step-by-step explanation:
Given the system of equation;
5x + y = 9 ... (1)
3x + 2y = 4 ...(2)
We will solve it simultaneously to get variables x and y.
Using substitution method,
From equation 1, y = 9-5x ...(3)
Substituting equation 3 into 2 we will have;
3x + 2(9-5x) = 4
3x + (18-10x) = 4
3x + 18 -10x = 4
3x-10x+18 = 4
-7x+18 = 4
-7x = 4-18
-7x =-14
Dividing both sides by -7, we will have;
-7x/-7 = -14/-7
x = 2
Substituting x = 2 into equation 1 to get y we will have;
5x+y= 9
5(2) + y = 9
10+y = 9
y = 9-10
y = -1
Therefore x = 2 and y = -1 is the solution to the simultaneous equation.
